The problem is I don't know if we command enough respect in the eyes of these beasts to react with authority anymore. We have been proven vulnerable too many times. I believe the roots of this all started
1. When the Carter Administration flinched on attacking when Iran took our hostages in '79. Yes, the lives of those 50 government workers could have been lost in such an attack and hindsight is 20/20, but they knew the risks involved in accepting a government job overseas, and we should've gone right in after them. The aborted rescue mission later was just an incidental after-fact. That's when our respect in the world starting slipping. And 2. In 1983 when we lost 283 Marines in Beirut (figure may be slightly off) the Reagan Administration knew they could do nothing, and did nothing except to divert a gullible public's attention by going into the pismire island-country of Granada to satisfy their need to strike out at "something." But, ultimately, those (or the country/countries) responsible were never brought to justice either by litigation or military response.
Besides, Reagan and his cronies (including Bush, Sr.) were too busy covering their tracks of dealing arms to Iran as a gift for holding the hostages until he was assured of ascending to power...as soon as he lifted his hand from the Bible at his 1st inauguration, presto!...instant hostage release! But that's another story.
After these two events it was open season on Americans, and then their Western allies as well...solitary hostages, plane blasts, European airports, etc. Once they found out they could strike at the US and get away with it, there was no turning back.

And once a fanatic fuses politics with religion and is ready to die for their "cause," how do you stop them? I don't know if you can. Though squeamish about capital punishment, I've often said that after the first World trade Center bombing which I considered to be an act of war designed to destroy the towers and kill tens of thousands of innocent people, that the perps, immediately upon conviction, should've been marched against a wall on camera and executed by firing squad. Show them we will not fool around. But, of course, our sense of justice bequeathed these genoicidal maniacs to life terms in humane prisons...sex, drugs, and rock'n'roll. Unless they're in solitary for protection. If so I hope they immediately release these subhuman assholes to the general inmate population which I'm sure would be delighted to mete out thorough justice to them at this point. Yes, I believe in mercy and forgiveness, but there is a point where you have to draw a line in the sand, and I've reached it. The stakes are now clear...if you're an American, you die. Remember that cynical and insulting release of black hostages all through the '80's, as if African-Americans were going to fall for that ploy of differentiation. Well, the terrorists took care of that fable when they bombed the US embassies in Africa. But the problem is, it isn't just Americans...these genoical maniacs who think they speak for their Muslin God...they don't. And certanly not for the vast majority of the Muslin faithful, it really is a religion of peace, so I really fail to understand this constant slaughter of the innocent in the name of their God) are trying to take on the entire world...us, Russia, the Hindus in India, all of Western Europe, their own secular governments, everybody...it's just craziness! And the real problem is that if you convict and execute any of thes culprits they're very happy to be martyred for their cause, thank you, and are hailed and viewed as such...what's the point of killing people who are perfectly willing and happy to die? So where's the answer, people? I pray to see it...but I just don't know. And we can't afford to go out, now, and blast away at dubious targets like that grain factory in Sudan, or strike areas that will kill any innocent civilians.
(Saddan Hussein...who I think is very culpable in this attack...but his name is not mentioned enough...this IS after all, the one and the same Bush administration he went to war with in '91, why wouldn't he take another shot at it? But maybe the Bushes don't want anybody to consider this?...anyway, Saddam is still sitting pretty in his royal palace, thank you, while 100,000 or so of his countrymen have died around him as th result (directly or indirectly) of the Gulf War, including an estimated 40,000 children...which shows and proves you have to kill the head, not just the body, or it doesn't go away). Violate the international law of political assassination instead of all these "collateral" innocent lives, or, ultimately, what we're witnessing today? YOU BET!! GO FOR IT!!! We have the technology and trained covert forces to get it done! Any proven mass-murdered or war criminal...Saddam, Bin Laden, etc. I don't think we have a choice. Not any more. But, ultimately, too, the sad reality is, that as long as there are people willing to die in suicide missions, what can the world do? And,what, for God's sake, do these people WANT??? How did it come to all this?
