The Good Thing is These Guys are Stupid So FarBut I do not for a second believe that the Jihadi idiots (so far) are not determined; they are clearly pretty incompetent but they can fix that over time.
And we are incompetent. Just listen to the Mayor of New York stupidly declaiming that the Times Square bomb attempt might be about Obamacare, or Eric Holder idiotically ascribing the failure of the attempt to citizen vigilance; the failure was due to the incompetence of the bomber. The next one will likely be smarter.
They've had varying competence so far, at a generally poor level, but determination will cause them to overcome their natural deficiencies and get better at killing us.
I hope we have governments committed to stopping them. I thought so once, and am less sure now.
