While Donald Trump, the official Republican presidential nominee, has to first deal with his opponent Hillary Clinton, he may find himself in a peculiar situation if he’s elected. The situation? Going to war with North Korea. Would Trump do it? Would Hillary? With new tensions arising, Trump as the president may need to declare a fight earlier than expected…

North Korea’s top diplomat for U.S. affairs told The Associated Press on Thursday that Washington “crossed the red line” and effectively declared war by putting leader Kim Jong Un on its list of sanctioned individuals, and said a vicious showdown could erupt if the U.S. and South Korea hold annual war games as planned next month.

Han Song Ryol, director-general of the U.S. affairs department at the North’s Foreign Ministry, said in an interview that recent U.S. actions have put the situation on the Korean Peninsula on a war footing.

The United States and South Korea regularly conduct joint military exercises south of the Demilitarized Zone, and Pyongyang typically responds to them with tough talk and threats of retaliation.

Han said North Korea believes the nature of the maneuvers has become openly aggressive because they reportedly now include training designed to prepare troops for the invasion of the North’s capital and “decapitation strikes” aimed at killing its top leadership.

“The Obama administration went so far to have the impudence to challenge the supreme dignity of the DPRK in order to get rid of its unfavorable position during the political and military showdown with the DPRK,” Han said, using the acronym for North Korea’s official name, the Democratic People’s Republic of Korea.

“The United States has crossed the red line in our showdown,” he said. “We regard this thrice-cursed crime as a declaration of war.”
