I'm going to be offline for a few days, so I'm suggesting some links to reading material worth your time.
There are two items from Mark Steyn, a writer I can never read enough of, and two from Victor Davis Hanson, a historian who has forgotten more than I'll ever know.
All that intelligent reality can be somewhat sobering, if not outright depressing, so Frank Gaffney's blog on his book, War Footing, is linked here. You'll find ten viable steps America could take to proactively defend itself from Islamic terror--the operative word being "could."
