Just, dammit! Iranian missiles targeting us. How many workers' paradises do we have to contain to the south? Didn't the threat of atomic missiles die down after the end of the cold war and the strategy of Mutual Assured Distruction? Do we have to teach little kids, again, to duck under their school desk and cover their ears?
Kennedy scared the U.S.S.R. missiles out of Cuba but left Castro in place, to appropriate the labor and lives of generations of Cubans to come. Obama gives Chavez big wet kisses on the cheek.
For that matter, how long do we have to put up with Islamic expansionism? To them, we are infidels in a world which should be entirely under Sharia, and the best we should hope for is to be dhimmi.
Western civilization has been periodically plagued by Islamic predations necessitating taking up arms, as in the Crusades, among other things. Islamic incursions damn near made it to Paris, and to Vienna, and pretty much ran Spain before being beat back. Temporarily. President Jefferson read the Koran then went after the pirates of Tripoli. This sh8t isn't new.
Here's the deal. When faced with an implacable threat to your civilization, you either have to win, or you lose. You can't just contain and delay them, as has been the strategy of choice for 1100 years. You can't just beat them back. You have to beat them.
Oh, and by the way. Being dhimmi means becoming a member of a barely tolerated indigenous population eking out an existence on the margins of a dominant occupying population.
