Well, after WWII, America saved the world from the spectre of Communism, firstly by blunt threat of total nuclear annihilation (which was sadly never put in practice when it could be), then when it became impossible, by continuous overt and covert work to undermine it, until success in 1991.

I come from the Soviet Union and i know what i'm talking about. Blessed are those who never had to live under this dystopian system of dehumanisation and torture - and if not US efforts, sometimes heavy-handed and sometimes not so, a lot more countries if not all the world would be subject to it.

It won't be much of a 'conflict'. No one except US had much power to resist.
