If America gives up the fight against terrorism, how long before the rest of the world caves? Britain might hold out a little longer, Australia, too, but without the technical weaponry/firepower/manpower and the US bully pulpit, Europe as a whole would be long gone, then Phillipines, Indonesia, etc.. Who'd be left standing? North Korea and China? South America? NZ? Not to worry, since this won't ever happen.
The oppressors, the evil ones.
