A majority of the American public thinks it is likely that Donald Trump will get this country into a war -- either a bigger involvement in current wars, or a new war. The general public, women, those under age 45, and Blacks all have majorities believing that -- and the other groups have pluralities.
This opinion was shared before Trump attacked a Syrian air base with about 59 cruise missiles. I doubt that action has lessened the public's view. It has probably increased it.
The chart was made from information in a new Economist / YouGov Poll -- done between April 2nd and 4th of a random national sample of 1,500 adults (including 1,331 registered voters), with a margin of error of 3.2 points.
