Uhhhh... you DO realize Republicans have been screeching about a new civil war for years, right?
There is a HUGE portion of this country that would ABSOLUTELY bomb their neighbors if they could get away with it. A civil war might not destroy everything, but that's only happening to the Palestinians. The US is too big to repeat that travesty.
That's exactly what they want you to think! Muahhahah
Seriously though... It's not REALLY the US that's doing these things... It's the global oligarchy... They just use American soldiers because we were the only ones left with any after WW2 and it stuck. The oligarchy has no allegiance to any country or people and would absolutely bomb the shit out of America if it profited them.
