I would tend to agree
A co-worker of mine ruminated this morning about what kind of action might have to be taken to silence liberal voices should another attack occur. It makes me think that while the terrorists may not win, we probably won't either.
Another highly visible attack on America would bode very ill not only for us and those who mean us harm, but for the entire world, I think.
FWIW, though, I don't see the Spanish decision as either cowardice or capitulation. Spain's seen longstanding popular opposition to the Iraq war and it was expressed in an election. They are trying to mitigate the effects of what many people see as a tragic mistake.
