It's worth noting Trump was the first US President to not start a war in half a century.

And Obama more than Bush. Either way, the direction is monotonically increasing. Could it be the problem isn't who holds the presidency?
I do think there's a chance that just having the capability is inherently corrupting. I guess we'll see how Biden does, though.
Now, I should perhaps qualify the above, since there are reasons to believe that Trump was not really able to get his way, foreign-policy-wise, due to military-intelligence-industrial complex objections, plus his defense secretary, head of the CIA etc (poor staffing which is mostly on him).
