Say that WW1 never happens and we get to the late 1920s with no conflicts in Europe. However in this time the USSR begins to expand and Western Europe begins to get a little scared. Also assume that with no WW1 the US stays isolationist and basically keeps to themselves on their side of the Atlantic. In this scenario would it be plausible for there to be a warming of relations between the UK, France, and Germany and possibly even an alliance between them to counter a more aggressive and expansionist Soviet Union? Or is the tension between them just never going to disappear without a war?
If this is plausible, could it perhaps lead to an earlier European Union to counter Soviet influence in Europe?
