A few quick thoughts...

Can you provide an instance where Trump's individual action prevented a military engagement or war that was actively lobbied for by leading Republican figures?

It seems unlikely for a President to start a military engagement without the support of their closest political allies and constituents. So it would seem that blame for previous wars should fall across both Congress and the President, and you can no doubt agree that many of the same Republicans (and Democrats) are in the same seats that they were then.
