Only 23 percent of Americans said otherwise, the survey found.
61 percent of the respondents said they see diplomacy as the best way to halt North Korea’s weapons programs, while 27 percent said that threatening military action is Trump’s best bet.
Overall, voter disapproval of the US president’s handling of North Korea is on the rise, from 45 percent in July to 50 percent in August and 55 percent in September, according to the poll.
Trump and the North Korean leadership have exchanged numerous threats recently, as the North continued its testing of ballistic missiles, including one of a reported hydrogen bomb.
Last Saturday, Trump tweeted that North Korean leader Kim Jong-un, whom he called Rocket Man, “won’t be around much longer.” North Koreans took it as a declaration of war, saying Pyongyang could shoot down US bombers “even when they are not inside the airspace border of our country.”
The White House later denied that the US had declared war on North Korea.
At the UN General Assembly last week, Trump threatened to “totally destroy” the North, if it attacked the US or its allies. Pyongyang responded with more threats.
Two permanent members of the UN Security Council – Russia and China – insist on the US dialling down belligerent rhetoric toward the North and pursuing negotiations.
