It was only the thread of the Soviet sphere of influence, and to that extent the famous urging of Churchill's 'Iron Curtain' analogy, that changed that policy. Otherwise, the US would have likely gone back into it's shell, so to speak.

Then there is the point that except for the TR years, the US was essentially isolationist before WW1 as well.
