I don't think it would. The US ceasing its awful meddling would much improve the general atmosphere.
How many military bases do they have parked on foreign lands? How many hands have they had in regime changes across the world? How often have they acted in a country without the permission of the host state? How many innocent civilians have they killed through their bombs?
You can bring up Russia and their bombs too, but without US meddling, they'd be much less requirement for Russia's bombs (who in this case are acting with permission of the elected government of Syria).
Trump would do a deal with Russia which would be financially beneficial to the US budget, beneficial to the Superpower claims of Russia and arguably beneficial to the world generally in terms of stability.
At least, let's try it this way, for the political-establishment way sure isn't helping much.
