Sooner or later the Communist/Islamic portion of America will go to war with Israel and defend its Islamic allies. However, at this time, America will fall into civil distress and another Revolution will be born and the Pro-Israel/Pro-Freedom Americans, who will be considered "rebels" will join sides with Israel and fight the tyrannical/fascist/Islamist America.
I see very dark times ahead and a lot of bloodshed. The Civil War in the 1800s will be nothing compared to what is on the horizon.
