Tabs, surely you jest? Was WWII against an ideology? Was the cold war against an ideology? Surely You don't believe what you said. Every modern major war was won by killing civilians, sad but true. Sherman fought few rebel troops on his march to the sea. He fought & killed & burned & stole the posessions of civilians. When we & the Russians blasted Berlin into submission many more civillians died than did military, as also happened in most of the allied bombing if Germany. In Hiroshima & Nagasaki relatively few military were killed, again civilians paid the toll.
If you really believe what you said then our only hope is to surrender & convert. I believe that the USA can defeat any force on earth once sufficiently motivated. When we make it hurt bad enough, as was done in the Civil War, WWII Europe & WWII Japan, trust me, they will succumb. It's all a matter of will.
