The United States was (and is) morally justified in military strikes against those who supported Al-Q. Period.

How specifically that should be done/prioritized/etc. is up to the military experts. I'm not suggesting that we should take action every single time it is justified - but the fact remains that it all starts with a moral case to defend ourselves.

Let's go back in time.....and one of the reasons why I don't get all giddy about Ronald Reagan.
When terrorists (supported by Iran) attacked Beirut in 1983, Ronald Reagan did NOTHING.
Even the French launched air strikes against the Iranian National Guard. We did NOTHING.
