NBA Click & Roll: Why the Warriors are vulnerable this postseason

  Golden State Warriors center Jordan Bell (2) dunks against the Phoenix Suns during the second half at Talking Stick Resort Arena.

This is where we bring you exclusive content from USA TODAYs NBA reporters Sam Amick and Jeff Zillgitt, including updates on all their exploits on the NBA beat. Plus, we catch you up on the *biggest* moments, quotes and news from the week. .

QUICK DISH: THINGS YOU MAY HAVE MISSED. - The Warriors are in the infirmary.

Kevin Durant is out at least another week with a rib fracture; Klay Thompson has a fractured thumb and will be re-evaluated on Thursday; Steph Curry is targeting a return later this week after rolling his right ankle. again. .

The playoffs start in less than a month, and for the first time in years, the Warriors are vulnerable.

- Their biggest threat is clearly Houston, which is running away with the No. 1 seed and boasts the best offensive player in the NBA. James Harden, thy name is MVP. .

- But what about Portland and Utah? Both small-market franchises have distinguished themselves in the loaded Western Conference by running off a combined 36-5 record. Do not overlook them as challengers to the Rockets and Warriors. .

Portland Trail Blazers guard Damian Lillard (0) dribbles around Houston Rockets guard Eric Gordon (10) during the third quarter at the Moda Center. The East is getting hairier by the day.

- While the Raptors go about their business -- getting a wonderful Office-style parody -- the Celtics have to be concerned with Kyrie Irvings knee. Hes been out for more than a week and will get a second opinion on his balky knee. .

- And then theres the Cavs. Coach Ty Lue announced he was taking a health leave due to chest pains and other troubling symptoms. Jeff reported he could be back by the end of the month.

Next, news broke late Tuesday night that Kyle Korvers brother had passed, and hes been excused from the team. They did get Kevin Love back from his fractured hand. .

- Hardly any team has been immune to injuries, and with the postseason on the horizon, injuries are beginning to define the playoff race.

- In lighter news, were not entirely sure what Love is doing here, and neither is he. And Cavs PG Jordan Clarkson made a startling admission. He thinks dinosaurs were once pets for giant humans.

- LeBrons recruitment has gone international. Yes, hes being recruited in New Zealand and the Philippines. Cleveland Cavaliers forward LeBron James (23) dunks the ball against Portland Trail Blazers in the first half at Moda Center.

- In extremely disrespectful fashion, James sent Portland center Jusuf Nurkic back to Bosnia with this jam. James is 33 and not entirely human. .

- We know the Kings dont provide much entertainment value, but youve got nothing better to do than wolf down mouthfuls of mayo? .

- Imagine a world where kids 11-and-under cant take a three-pointer and dont know what the phrase zone defense means. Thats essentially what the NBA and USA Basketball have recommended. .

- Gordon Hayward continues to flirt with the idea of a comeback, but regardless of whether it happens or not, Thunder star Paul George, who suffered a gruesome leg fracture of his own, has kept in touch with the Celtics forward.

He knows Ive got his back, he said. . - An ex-Mavericks employee who said she was harassed by former Dallas CEO Terdema Ussery isnt convinced owner Mark Cuban is aware of the culture hes helped create.

- Former NBA All-Star Steve Francis was arrested Sunday night for public intoxication just weeks after penning a gut-wrenching essay about how drugs and alcohol affected his life.

- The Lakers have actually played well since acquiring Isaiah Thomas from Cleveland, but the headstrong guard remains adamant that hes no sixth man.

Los Angeles Lakers guard Isaiah Thomas (3) drives to the basket against Miami Heat forward Kelly Olynyk (9) and forward Justise Winslow (20) during the second half at the Staples Center.

- Jeff talks with legendary NBA scribe Sam Smith about his latest book on the NBA A to Z podcast.

- While the list of NBA prospects who have already been eliminated from the NCAA tournament is a long one, theres still plenty of talent left in the field. We take a look at the best 16 NBA prospects still dancing. .

NBAS VERSION OF MARCH MADNESS. This weeks power rankings — which feature Portland all the way up to No. 4 and Utah up eight spots from No. 7 — highlight the leagues chaos as we approach the final few weeks of the season. .

Why Only 9 Countries Have Nuclear Weapons (feat. It's OK to be Smart!) - Duration: 7:24.

(light music)

- Nuclear weapons, they're a lot like

Pirates of the Caribbean movies.

There's way to many of 'em,

we certainly don't need any more,

and if you actually think about what goes

into making them, they're pretty scary.

I mean come on, Johnny Depp, I mean the first one was cool,

but after that it was just to waste everybody's time, man.

But anyway, nuclear weapons have been around

for more than 70 years.

And despite numerous negotiations and treaties

to get rid of them, they're not going away anytime soon.

(upbeat music)

If you follow the news to hopped on Twitter recently,

you really can't escape the feeling that nuclear war

might be on the horizon.

In a New Year's Day speech, North Korean leader,

Kim Jong Un, boasted that and I quote,

The entire mainland of the US is within range

of our nuclear weapons and the nuclear button

is always on the desk of my office.

President Trump Tweeted a response that he too,

had a nuclear button at his desk, that much bigger.

Then less than two weeks later,

people in Hawaii received this emergency alert

on their cell phones.

(siren wailing)

It turned out to be a false alarm,

but worries about a nuclear armed North Korea are no joke.

In September 2017, the country successfully detonated

the largest nuclear bomb it had ever tested.

The international community's no fan

of North Korea having nukes.

They'd prefer they didn't have them at all.

In fact, North Korea's one of only nine countries

that has nuclear weapons.

So how did we get here?

Why do some countries have nuclear weapons,

while others don't?

Before we dive in, let's hear from Joe Hanson

over at It's Okay to Be Smart,

about why nukes are so dangerous.

- Nuclear weapons can unleash a level of destruction

that's pretty much unmatched.

Conventional bombs rely on chemistry to create explosions.

The ingredients inside a conventional bomb

transform one set of chemicals into another,

releasing energy along the way.

Nuclear weapons however, derive their destructive power

from altering the atoms themselves.

These nuclear reactions can take two forms.

With fission, one atom is split into two new atoms.

The two bombs the US dropped on Japan on World War II,

were fission bombs.

They killed more than 200,000 people.

Fusion on the other hand, combines two atoms into one.

These hydrogen, or thermonuclear bombs,

have the potential to be a thousand times more powerful

than fission bombs.

In 1961, Russia detonated a fusion bomb

that was 10 times more powerful

than all the conventional weapons used in World War II.

But with nukes, the massive explosion,

vaporizing heat blasts and immense shock wave,

are only part of the damage.

All that fusioning and fissioning

also releases huge amounts of radiation.

This mutates DNA, kills cells,

and if it doesn't poison you immediately,

may eventually lead to cancer.

The destructive power of atomic weapons

is so great, the clouds of ash and dust they throw

to the sky may even block enough sunlight

to create a so-called nuclear winter.

Contributing to the destruction of whole ecosystems.

You can see why these are looked at as cruel bombs.

- It may seem crazy that we created

these insanely destructive weapons at all.

But when they were first being developed,

it was a crazy time.

Let me set the scene for you.

Late 1938, just nine months

before the start of World War II,

scientists in Nazi Germany accidentally

discovered nuclear fission.

Physicists had known for about 40 years that an immense

amount of energy was locked inside the atom.

But here, finally, was a way to unlock it.

As news of the discovery spread and World War II began,

every major industrial nation raced

to build their own atomic bombs.

The US got there first.

In 1945, on a summer night in the desert of New Mexico,

they tested the world's first atomic bomb.

It took some of the brightest scientists of the day

and over 22 billion dollars in today's money

to make it happen.

Because these bombs cost so much to develop

and require such advanced technology,

only the richest and most powerful countries

were able to make them.

By the mid 1960s that was a small club.

Only the US, the Soviet Union, Great Britain,

France, and China had nuclear weapons.

But then, the Cuban Missile crisis happened.

In 1962 it looked like nuclear war might just happen.

It was discovered that the Soviets had nuclear weapons

in Cuba that were pointed directly at the US.

War never happened, but the 12 day crisis

that freaked out the world

eventually led to the landmark

Treaty on the Non-Proliferation of Nuclear Weapons in 1968.

The core of the treaty states that had nuclear weapons

would take steps to get rid of them,

and countries without nuclear weapons won't try to get them.

In the decades that followed,

nearly every country ended up signing the treaty,

With few notable exceptions.

India, Pakistan and Israel.

North Korea did sign, but withdrew in 2003.

All four of these countries went on to develop

their own nuclear weapons.

Today it's estimated that there are approximately

15,000 nuclear weapons in existence.

Now that may sound like an insanely large number,

but it's actually down from a peak of 70,000

in the late 80s.

Russia and the US own about 93% of all nukes.

The remaining 7% is owned by just seven other countries,

China, France, the UK, India, Pakistan,

Israel, and North Korea.

Many countries without nuclear weapons don't want them.

They might be allies with countries that do have nukes,

or maybe they're not interested in spending

a bunch of money developing and maintaining them.

But for countries with nukes,

it doesn't mean that they're itching

to start a nuclear war any time soon.

The goal isn't to use them.

Instead, it's part of a larger strategy

to discourage other countries from attacking them.

It's called the Deterrence Theory.

And has been a heated topic of debate for decades.

To illustrate how it works,

let's look at the ultimate nuclear rivalry.

The US verses Russia.

Basically, a nuclear attack is so destructive

that Russia would never directly attack the US,

because the US could respond with an attack of their own.

But for this to prevent war,

Russia would also need nuclear weapons

so the US couldn't attack them.

Since neither country could attack the other,

both will be forced to use diplomacy

to solve any disagreements.

You know, they basically just have to talk it out.

In his 2008 State of the Union Address,

President Trump singled out deterrents as a key reason

why the US should keep its nuclear weapons.

- We must modernize and rebuild our nuclear arsenal

hopefully never having to use it,

but making it so strong and so powerful,

it will deter any acts of aggression.

- Supporters of the Deterrence Theory,

argue that it has kept the world safe.

In the nearly 70 years that countries have had

nuclear weapons, there's been no nuclear attacks.

However, more and more think that the theory

doesn't hold up in the modern world.

The risk of an accidental launch or a terrorist group

getting its hands on a nuke is way too high.

Think about it.

If a suicide bomber were able to get a nuclear weapon

would they really be deterred

by another country that had them?

If we're ever really going to be safe,

these critics thing we need to get rid

of all nuclear weapons.

Okay guys, so this is more than just another history lesson.

Right now, as you're watching this video,

the US is planning on spending over one trillion dollars,

trillion with a T.

Over the next 30 years to modernize their nukes

and stay ahead of the game.

What do you guys think about that?

As always, let us know in the comments below

and like and subscribe.

Oh yeah, first of all, we gotta thank Joe

at It's Okay to Be Smart for you know,

coming on and sharing all that information with us.

Thank you Joe, you're awesome.

If you guys haven't checked out his show,

you should do that.

And if you like this video,

you should check out internet trolls

because people just say mean things on the internet.

And you should watch facial recognition

because they're keeping tabs on us, guys.

Remember that.

Stay Above the Noise, til next time guys, bye.

Trump uratował Melanię przed sporą wpadką. Jest nagranie [SZOK] || LVTplotki - Duration: 2:54.

Trump uratował Melanię przed sporą wpadką. Jest nagranie

O tym, że małżeństwo Trumpów przechodzi poważny kryzys, spekuluje się już od dawna.

Po aferze, w której na jaw wyszły zdrady prezydenta USA, mówiono nawet, że pierwsza dama może niedługo złożyć pozew rozwodowy.

Na oficjalnych spotkaniach raczej trudno było się doszukać choćby drobnych oznak czułości.

Jednak ostatnio Trump miał okazję uratować Melanię przed sporą wpadką.

Zobaczyć obejmujących się Melanię i Donalda Trumpów to prawdziwa rzadkość.

Para raczej stroni od okazywanych oficjalnie czułości.

A po ostatnich rewelacjach związanych z romansami Trumpa z gwiazdą porno Stormy Daniels spekulowano nawet o tym, że Melania wkrótce rozwiedzie się z mężem. .

Media zagraniczne kilka tygodni temu wychwyciły, jak prezydent chciał chwycić żonę za rękę, która jednak pozostała niewzruszona na gest męża.

Ale ostatnio doszło do incydentu, który wzbudził spore zainteresowanie w mediach społecznościowych.

Para wspólnie zmierzała do helikoptera gdy nagle Melania potknęła się i omal nie upadła.

Na szczęście Donald uratował sytuację i pierwsza dama uniknęła sporej wpadki.
