The poll was conducted about a week after Trump intensified rhetorical exchanges with his counterpart Kim Jong Un, dubbing him "Rocket Man" and threatening in a September 19 speech at the U.N.to "totally destroy" North Korea if the U.S.is forced to defend itself and its allies.

Those are the findings of a poll by the Associated Press-NORC Center for Public Affairs Research, as tensions between the adversaries escalate and North Korea comes closer to its goal of having a nuclear-tipped missile that could strike the continental U.S.

A U-2S high-altitude reconnaissance aircraft has been deployed by the U.S. Air Force to monitor potential military movements by the North.

Tensions spiked on the Korean Peninsula in August as North Korea announced a plan to launch ballistic missiles toward the US Pacific territory of Guam. Almost two million South Koreans visited the spot over a decade, according to South Korean government figures.

After entering South Korean airspace, the two bombers carried out air-to-ground missile drills in waters off the east coast of South Korea, then flew over the South to waters between it and China to repeat the drill, the release said.

The B-1Bs also conducted exercises with Japan's Air Force in what the USA statement called a "sequenced bilateral mission".

He said: "Our big concern is, with regard to North Korea, that it is very unlikely the North Korean dictatorship is ready to agree to an global agreement to renounce the building of nuclear weapons if the only agreement in the world that has allowed such a renunciation is at the same time called into question".

Trump hosted a discussion on Tuesday on options to respond to any North Korean aggression or, if necessary, to prevent Pyongyang from threatening the United States and its allies with nuclear weapons, the White House said in a statement.

"Our country has been unsuccessfully dealing with North Korea for 25 years, giving billions of dollars & getting nothing".

Australia's top diplomat visited the heavily fortified border between the two Koreas on Thursday and said her government hopes there will be no need for military action against North Korea over its weapons programs.

"We reiterated our support for our collective strategy of maximum diplomatic and economic pressure on North Korea so it will be compelled to return to the negotiating table". "Policy didn't work!" the US president said in a Twitter post on Monday.
