Without nato there might just be a world of nations not obsessed with fending off the big bad reds, we might heal from 2 world wars before dropping the big one. And maybe fascism can be stopped in families schools and corporations before it kills anyone else and maybe the BRICS and G7 can stop trying to act like the economy is a football game and maybe the usa will drop some of its phony imperialist arrogance and learn some real national honor and backbone.Also the west might get some humility about what actually requires any military action.Terrible answer I know.

Guess it depends on the service agreement, but this would be huge leverage for Europe. I do wonder if Europe has the capacity to exercise power anymore.
