TA,
My liberal cohorts aren't answering your question because it's a ridiculous question that sets a rhetorical trap based on a false dilema logical fallacy.
The answer to your question, of course, is yes.
But allow me to illustrate how absurd and useless your scenario is:
Would you support a rollback of Bush's tax-cuts if it was the only way to keep a nuclear bomb from being detonated in NYC?
Would you vote for Kerry if it was the only way to keep a nuclear bomb from being detonated in NYC?
Would you support socialized healthcare if it was the only way to keep a nuclear bomb from being detonated in NYC?
Would you support a ban on assault weapons if it was the only way to keep a nuclear bomb from being detonated in NYC? (well...that one's probably a bad example...

)
The thing is, it is entirely likely that Bush's distancing from diplomacy in favor of a shoot-first-ask-questions-later-approach to foreign policy is breeding more animosity and anti-American sentiment which will in all likelihood breed more terrorists.
You seem to have such a juvenile, two-dimensional idea of what it means to be liberal. I get the impression that you believe that conservatives are anti-terrorism while liberals are pro-terrorism. It's absurd.
Imagine the following scenario:
You and I are roommates. We live in a house (don't worry, we're not having gay sex -- we're just roommates). Let's say that the house develops a nasty infestation of black ants. These things are really pissing you off. They're getting into your cereal, crawling up your pants. It's just a bad situation all around, and being the itchy-trigger-finger guy that you are you want to send all those black ---daisies--- to their graves.
So...I get home from work and see you unloading a bunch of jars from your car. I check it out and see that the jars are filled with red ants. You say, "Check it out Shmokes. Our problems are over. I'm going to release all these red ants in our house and, mark my words, within a week every last one of those black ants will be dead!!!"
I, being the liberal (read: thinker) in the household mount a protest. I contend that while you will certainly kill a lot of bad guys, your solution to our current problem could create a bigger problem for us in the future.
You, of course, just decide that I don't have the balls to do what is necessary to rid our house of the black ants. Then, to prove your point you ask me one last question (and then get really obnoxious when I refuse to answer it):
"Shmokes, if letting these red ants go in the house was the only way to keep yourself from getting cancer would you do it?"
