Will Trump change America’s nuclear policy?

Experts say there's really no way to stop a president's order to launch a nuclear strike

(CNN) – One of the biggest responsibilities Donald Trump will have as commander-in chief is having access to the nuclear codes. Does this make some world leaders nervous?

Take hold of America’s nuclear codes. He’ll be able to launch nuclear missiles with a single momentary decision. There are serious concerns about whether Trump wants countries like japan and South Korea to have nuclear weapons.

As a candidate, Trump said this. “Wouldn’t you rather in a certain sense have Japan have nuclear weapons when North Korea has nuclear weapons?”

A few days later- he went back on that. Sort of.

Donald Trump, “Japan should have nuclear.’ That’s what I said, supposedly? I didn’t say that. I would rather have them not armed. But I’m not going to continue to lose this tremendous amount of money. And frankly, the case could be made that, let them protect themselves against North Korea.”

Anti-nuclear advocates say the uncertainty- is dangerous.

Joseph Cirincione, Ploughshares Fund said, “Japan is in crisis. South Korea is in even- in a more-severe crisis. There are ultra-right nationalist forces in both countries that want nuclear weapons. The President of the United States must be absolutely clear that we do not want them to do that. That is not the path to security in Asia.”

We asked the Trump transition team to clarify the president-elect’s position. We haven’t heard back. Some of Trump’s national security critics say they’re outright scared, about him having the nuclear codes. They describe him as quick-tempered, prone to lash out.

Donald Trump, “I would bomb the s*** out of them.”

President Barack Obama, “If your closest advisors don’t trust ya to tweet, how can you trust him with the nuclear codes? You can’t do it.”

Trump told NBC he’ll be responsible with the codes.

Donald Trump, “I will not be a happy trigger like some people might be. I will be the last but I will never, ever rule it out.”

The moment he’s sworn in, Trump will have several potential nuclear crises to deal with. Tensions between Vladimir Putin’s forces and NATO are escalating.

North Korea’s belligerent dictator, Kim Jong Un, already has nuclear weapons that can threaten his neighbors and tens of thousands of US troops in South Korea.

If there’s an alarm even a false one Trump would have only a few minutes to decide whether to launch nuclear weapons, or hold back.

Pete Metzger is a former marine who carried the nuclear football, the satchel with launch-codes, for President Reagan.

Pete Metzger, Carried ‘Nuclear Football’ for President Reagan said “The result of a decision the president would make is so grotesquely horrible, so grotesquely horrible, it would change the face of the Earth, it would change humanity, it would change mankind.”

Experts say there’s really no way to stop a president’s order to launch a nuclear strike. Metzger says it would take full-on mutiny.
