Yes, it is not quite that easy and what is true is that military victory is now a given. What has rarely been understood is that victory gives you the practical opportunity to reshape the political life of the opponent and its economy as well. It is here that failure has been abundant.
It should not have been. We have excellent examples in Germany and Japan. Even Russia's flawed ideas did work after a fashion. Yet we forgot that both focused on removing the elite culture that nurtured the war and fostured a new elite culture to help it. Then it stayed in place until it was deeply entrenched.
Islam is not a different matter at all. These countries must be changed from top to bottom as was done in Turkey. Do you serously think that Germanhy would be useful had we a Nazi party intact and recruiting?
Both the ideology and the political form of Islam must be suppressed. It is not religion nor is is divine revelation when murder is rationalized..
The biggest mistake was the presumption among US political and military leaders that victory was ever possible
the odds of the US coming up a winner in a modern war are perhaps as low as one in seven
