Well, that's part of it, though, right? Nobody thought (rightly) that the US had anything more in it than a genuine NEED to destroy Al Qaeda. That's what they did, and now other nations are actively involved in helping to rebuild. I think the fact that the UN sanctioned it certainly did help.
"Terrorism" is why there's no peace in the middle east? I think you're mixing cause and effect, and badly. There have been FIVE RECENT WARS involving the state of Israel. The existence of the state of Israel is why there's no peace in the Middle East. The terrorism is there because nobody can challenge the power of Israel anymore. Right? Come on. You're right about one of the reasons why the US is being lashed out at though - continued, practically unquestioned support of Israel.
As for states that sponsor terrorism, this can easily be dealt with under the UN Agreement on Human Rights. The UN *should* be more firm with these states, but as we've seen, intelligence can be very faulty or spun to support all kinds of things. Not that I doubt these states are terrorist-supporters, and not that I think we should leave them alone. I think we should act STRONGLY to stop their actions. But, through the UN. Of course, THE US could act through the UN, and did for Afghanistan. I'm not sure that military intervention is in anyone's best interests with regards to these nations, necessarily, but the US should, if they're game, try to mobilize the UN to act. It's not like the UN is some *wholly* separate entity - in many cases, it (meaning the other member nations) does what the US wants. Why isn't the US pressing other nations for multilateral action on these rogue stats - using the UN as it was meant to be used?
No chance are terrorists more dangerous now. What kinds of weapons? This century has started out to be the *least* dangerous in terms of terrorism - *even factoring in 9/11*. (Not the least dangerous to people in North America, mind you - but there's the rub. And outside of 9/11, we're not really suffering yet, are we?) Let me say that terrorism can include *state-sponsored* terrorism, and thus includes all kinds of genocides of the worst kind from the past century. Anyway, what kinds of weapons? If you want to start another WMD discussion, we can, but let me say at the outset that it's a myth - the best weapon a terrorist could get their hands on today, after a nuclear weapon, would be a pile of explosives. There's no threat from biological or chemical weapons that anyone should be concerned about.
DON'T BUY IT FOLKS. There is no war on terror, nor is there a need for one.
There are lots of terrorist groups outside of Islamic terrorists, and tons of Islamic terrorists are NOT interested in suicide.
