WW3 is already here, of course. And you're right, we won't win it until we stop trying to accomodate those who hate us.
No, it's not WW3 yet, I'm thinking if we don't broaden our horizon in the understanding of the larger intrigue in the world we won't be around for WW3.
The U.S. could easily suffer a simultaneous attack from serveral directions, N. Korea, Iran, India, Brazil, even France. We go around assuming their missles can't reach us, but each of these nations has close or growing ties to China, and thanks to Willy, we have put them even with our missile program and I have heard that the Chinese still have access to our labs.
If we go down, it will be due to corruption within. The void created in the world by our demise would place world power up for grabs between the U.N., the E.U.,Russia, and China.
The E.U. and the U.N. would gain control of the elements of our military stationed overseas along with our subs.
Biblical prophecy says a nation very much like China with an army of two hundred million wipes out a third of the earths population before it is finally defeated. The actual WW3 will be quite a sight, I'm not that sure we will be around to see it though.
