Exactly where did I say that NATO was preventing that (i.e. takeover by Islam)?
You said, and I quote, "The U.S. still has a role to play in any alliance to the extent that we have an interest in a free Europe (i.e. one not completely taken over by Islam)."
If NATO is not furthering that goal then what role to we play by remaining in it? And if Europe is not interested in avoiding a Muslim takeover then what can we do to prevent it?
