The combination of Donald Trump, Twitter and nuclear weapons seems to be enough to send chills down some people’s spine.

President-elect Trump on Thursday tweeted out that he wants to “greatly strengthen and expand” America’s nuclear arsenal, on the grounds that it would make the world “come to its senses” on reducing the number of nuclear weapons it produces.

The United States must greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes

The timing of Trump’s tweet is interesting because it came after Russia said this week that it was looking to strengthen its own nuclear capabilities to be able to penetrate missile defense shields.

Regardless, Trump tweeting about nuclear weapons was enough to set off panic across the internet — some choice reactions to Trump’s tweet follow below.

Donald Trump is repeating Nixon's Madman theory of nuclear deterrence but with an actual-ass madman in charge.

Problem: The world needs to come to its senses about nuclear weapons.

Trump’s Solution: More nuclear weapons for us!

This makes no sense.

It also doesn't make me feel any better that Trump won't start a nuclear war.

We're all gonna die. https://t.co/lRWq8kYZEr

Based on Trump's tweet re: nuclear capability, he must have hired Dr. Strangelove as his adviser on nuclear policy. #trump #drstrangelove pic.twitter.com/ZEklzl1y8W

On a more serious note, nuclear arms expert Joshua Pollack outlines why such a strategy is unlikely to reduce the total number of nuclear weapons in the world:

You can spend unlimited sums chasing nuclear primacy, but can't catch it. A tweetstorm in six parts: https://t.co/UG7jpwsfG0

This message implies that other countries – "the world" – have to be the adults when it comes to nuclear restraint. https://t.co/X5gLlYZYKE

But is there any doubt that Russia can keep up with America in nuclear numbers? This is one reason for bilateral arms control: to cap costs.

This is a game that many sides can play. There is no last, winning move when it comes to arms-racing. (END)
