Sounds quite plausible to me. Another, additional, point of dispute could be greater US insistence on something similar to the Marshall Plan post-WW1. I seem to recall they did try, albeit not strongly, to dissuade the European allies from taking punitive measures against Germany & Austria-Hungary after WW1 - just take that one or two steps further.
Next point: Does there need to be a "bad guy"?
I doubt any nation or alliance has ever though of itself as the "bad guy" prior to or during a war (if ever), quite the reverse, in fact. Also, it appears to me, that most wars have, actually, been fought between either two sets of "bad guys" or two sets of "good guys" with very few real "good guy - bad guy" conflicts (WW2 being one of those few exceptions).
The base causes of most wars are population pressure, food production & trade (which actually relates closely with the previous two). Technology, also, plays a part - largely by increasing the pressures which build up due to these causes before they need to be released. There are sub-plots of religion, politics & tribalism/racism thrown in there but the base causes remain pretty constant.
