Probably, but while some people from the Middle East may fly planes into office towers, not all Middle Eastern people fly planes into office towers.
The point is that there are no people who are not from the Middle East who fly planes into office towers.
And since it's impossible to know which are which, the best policy is to suspect them all when it comes to national security interests. That may sound 'intolerant' in these multi-cultural times, but even the liberals of the 1940's understood the concept that precious few Japanese could be really trusted until the war was over. But Americans still had brains and common sense back then, something that seems in short supply today.
If only the terrorists had a big "T" branded on their forehead we could easily tell which ones were which. But lacking that, it is difficult to distinguish the good from the bad. I personally don't have much fear that anybody in the UAE Royal family is going to be involved in terrorism but I think it is likely that they have plenty of America hating Islamofacists in their employee.
No, but a good portion of the rest of them dance around in the street and celebrate while burning U.S. flags.
Gee, I don't remember when we had our last "Burn the Saudi Arabian flag and ululate" block party.
