Relations increasingly tense minister Donald Trump with Pyongyang has shaken members of Congress to the point that three Democratic senators announced a bill on Wednesday would get to ban Trump and without first nuclear or conventional nuclear weapons with North Korea attack approval by Congress.

Sen. Chis Murphy (D-Conn) Twitter a series of messages on proposed regulation, which will rise with men. Brian Schatz (D-Hawaii) and Cory Booker (D-N, J ..).

“My bill … makes clear that any pre-emptive strike against unauthorized, nuclear or conventional North Korea is illegal,” Murphy wrote.

“Trumps threats from North Korea are real,” Murphy wrote. “Triumph mistakes could kill hundreds of thousands on the Korean peninsula.”

The disagreement between Pyongyang and Washington has accelerated further in late months ahead of Trump’s visit to South Korea in November.

This month, Kim warned in Ryong, the UN deputy ambassador to North Korea, before the UN General Assembly disarmament committee that a nuclear war can at any time “break up.” While bragging of the country is relatively normal, the equally destructive rhetoric of the White House has begun to stir those at home and abroad.

Earlier this week, Japan’s Defense Minister said Itsunori Onodera United States and South Korea that North Korea, the threat of a “critical and immediate level” had grown, according to Reuters, and called his colleagues to help to control the antagonistic nation.

White House officials have the option of keeping diplomacy open, even though the United Nations has imposed harsh sanctions on North Korea. Chancellor Rex Tillerson said earlier this month that the United States would be willing to negotiate with Pyongyang “until the first bomb.”

Trump will travel November 7 as part of his Asia tour to South Korea, where “permanent alliance and friendship” will be held between Washington and Seoul. It is unclear whether Trump will visit the demilitarized zone of Korea on his trip north and frown as Vice President Mike Pence earlier this year.
