The chart above is from the Economist / YouGov Poll -- done between March 18th and 20th of a random national sample of 1,500 adults, with a margin of error of 3.1 points. It shows that a majority of Americans (53%) think it is likely that Donald Trump will get this country into another war.
They could be right. Trump has made threats toward both Iran and North Korea (and Venezuela), and has given the impression that he is itching to attack one of those countries -- most likely North Korea. A war would not only satisfy his narcissistic tendencies (thinking he knows better that everyone else (including the Pentagon and foreign policy experts), but I think he believes it would take everyone's mind off the Russian investigation and get the people behind him.
Until now, there have been cooler heads in the White House that have talked him out of such a foolish notion. But he has fired Tillerson and McMasters, and replaced them with Pompeo and John Bolton. Bolton (pictured) will be the new national security advisor -- one of the closest people to Trump.
That's bad. It's bad because Bolton is a war lover. He hate's the Iran treaty (and wanted to bomb Iran) and has already made a case for attacking North Korea preemptively. Bolton won't talk Trump out of starting a war. He'll talk him into it!
The world just became a more dangerous place, and the United States just moved a giant step closer to a new war (in spite of the fact that we still have two that we haven't finished). And Congress can't prevent this from happening. Bolton's new job doesn't require Senate confirmation, and Trump has to power to start a war without congressional approval.
