Trump Warns North Korea His Threats Were Not 'Tough Enough'

In his pillar to post threats against North Korea, the U.S. President Donald Trump has raised the bar once more by asserting that his warning of "fire and fury" earlier this week  may have failed to convince Pyongyang of his intentions.

"Maybe it wasn't tough enough," Trump told reporters while on his 17-day "working vacation" at his golf club in New Jersey.

He decried past administrations’ failure to act on the issue, stating it was time for a President who "stuck up for the country" and said North Korea, or the Democratic People's Republic of Korea, as it prefers to be called, would be “in trouble like few nations have ever been” if they do not "get their act together".

Hours after Trump had warned on Tuesday that any threat to the United States would be met with potential force, Pyongyang stated it had begun "carefully examining" the U.S. Pacific colony of Guam.

North Korea's statement also said its plan could involve involve firing medium- to long-range rockets at the Pacific island, which is home to a strategic outpost of the U.S. military including a submarine squadron, an air base and a Coast Guard unit.

"Let's see what he does with Guam," Trump said in reference to the North Korean leader Kim Jong Un. "He does something in Guam, it will be an event the likes of which nobody has seen before."

He added that the country should be "very, very nervous" if anything is done to the U.S.

Tensions between the two countries have escalated in recent weeks, after Pyongyang tested two intercontinental ballistic missiles in July.

In response, the United Nations Security Council approved new U.S.-drafted sanctions last Saturday.

This week, the Washington Post also reported that the North has successfully created a miniaturized nuclear warhead.

Korea was united before the U.S. war on the peninsula from 1950-1954 left the people on both sides of the border permanently divided.

The U.S. has over 37,500 troops stationed in South Korea.

Both nations' armed forces conduct war games off the coast of the region on a regular basis, which are regarded as a major provocation by the North.
