A little off topic, could you imagine which countries would come to aid the embattled US Government, and what armament they would bring? What our neighborhoods and homes would look like? In the US, CW2 would look more like WW3.
OTOH, Molon Labe. And a BLOAT for good measure.
I think to imagine CW2 you might look at elements of the Spanish Civil War of the 30s, Argentina in the 70s, and Ireland from the 70s to the 90s.
