We’ve had skirmishes and overseas engagements over the past several decades, but when was the last time the United States was involved in a major war?

Iraq? Afghanistan?

(Yes, I know we have some military buffs out there who are ready to chime in. I welcome them.)

A new NBC News/SurveyMonkey poll has found that a large majority of Americans are in fear of a coming major war.

The online poll found that 76 percent of Americans fear the U.S. will see a major war within the next four years, as opposed to the 23 percent who have no such worries.

With all that has happened since the beginning of the year, it appears the sense of security is eroding.

In February of this year, only 66 percent were in fear of a major war.

North Korea may be at the heart of the concerns.

Forty-one percent of Americans think North Korea poses the greatest immediate threat to the U.S.

Just 28 percent think the Islamic State in Iraq and Syria (ISIS) poses the greatest immediate threat to the U.S. and 18 percent think it’s Russia.

Fifty-nine percent of Americans now feel less safe from North Korea than one year ago. About one-quarter, 28 percent, say they feel about as safe from the North Korea threat as they felt in the summer of 2016.

In regards to how to deal with North Korea and the manic in charge of their nuclear ambitions, Kim Jong-un, 59 percent of respondents feel diplomacy is the name of the game. Another 35 percent feel military action is required to bring him under control.

If you break that down by party, the majority of Republicans polled favor military action, while the majority of Democrats prefer to talk it out.

This was a pretty large sampling, with 5,347 adult respondents. It was conducted between July 10 and July 14, with a 2.1 percent margin of error.
