Veterans explain why Trump is trying to goad Kim Jong-un -- and it's frightening

Earlier on Saturday, President Donald Trump took to Twitter with cryptic warnings that "only one thing will work" in his ever-growing tensions with North Korean leader Kim Jong-un.

"Presidents and their administrations have been talking to North Korea for 25 years, agreements made and massive amounts of money paid," Trump tweeted. "Hasn't worked, agreements violated before the ink was dry, makings fools of U.S. negotiators. Sorry, but only one thing will work!"

According to Vote Vets, a progressive veterans group, Trump may be trying to provoke the North Korean leader into striking first.

"We need to take seriously the possibility that Donald Trump is trying to goad Kim Jong-un into a first strike, so he can respond," the group tweeted later in the afternoon.
