In addition to what others said broadly. The moves he is making and allowing others to make if successful will cripple the US to the point where it eventually lead to barbarism or revolution, there will be no other choices and no options to continue the status quo as imperialist plunder will stop and the bourgeoisie will start devouring the labor aristocracy at home for profits out of desperation.

He isn’t doing it for those reasons but if you only care about purity of intent you’ll get nowhere in this messy world of ours as it stands. Its results we must care about, it is the material change and reality, not the best wishes and idealism which will bring about communism.

So in that respect, if this whole thing pans out and the US doesn’t pull out some masterful trump card, he will have had a large hand in helping the peoples of the world by no intentions of his own. Much like the German government helped communism by sending Lenin back on a train, it was not their intent for all that happened with the Soviet Union to follow but it was the actual material consequence of their actions.
