My personal opinion: what we're worried about is not an adverse reaction from our supposed "allies" in Arabia.
What we're worried about is the reaction we might see right here in the good ol' US of A.
Our federal gevernment has so thoroughly blown it, the CIA, the FBI, the INS, the FAA, the BATF, and all the others -- they ain't got NO idea who is running loose in THIS country or what their capabilities might be.
Right now, we're waiting for the other shoe to drop. If we retaliate against bin Laden et al -- we don't know what they could do. Underestimating your enemy is a serious strategic mistake.
Overestimating him is too.
I remember the "Fearsome Republican Guard" in the Gulf War, and those guys surrendered to news reporters.
I'm sure glad you dopes aren't running the country.
