Sen. Tom Cotton is warning that North Korea isn’t interested in relinquishing its nuclear weapons and can’t be trusted to negotiate in good faith, just as President Trump is preparing to meet with North Korean dictator Kim Jong Un without preconditions.

“We should be taking more steps than we are right now to be ready to fight a war, if that’s what’s necessary, with North Korea,” the Arkansas Republican said in an interview with “Behind Closed Doors,” a Washington Examiner podcast. Cotton, 40, is a combat veteran of the Iraq war.
