Diplomacy by raving maniacs

Everyone agrees that North Korea's Kim Jong-Un is hopelessly unstable and irresponsible in his leadership of North Korea (DPRK). But check out actual quotes from both the Jong-Un and Trump administrations and decide who is more unstable and irresponsible in leadership of their respective countries:

US: “North Korea is looking for trouble. If China does not help, we will solve the problem without them." 

DPRK:  "In the event of a U.S. military attack, our country would not scruple at launching a nuclear strike at US forces." 

US:  “We are sending an armada, very powerful. We have submarines, very powerful, far more powerful than the aircraft carrier. We have the best military people on earth.” 

DPRK:  “Thermonuclear war may break out at any moment. Any missile or nuclear strike by the United States would be responded to in kind that would reduce US military forces in South Korea and on the US mainland to ashes. The United States and its allies, should not mess with us.” 

US: “The era of strategic patience is over. All options are on the table.”
