If Al Qaeda remains true to form, they will now target the French and the Germans. It is hard to think of an attack that would not be good tactics when you believe that God is on your side.
These attacks just show huge misjudgement on the part of Al Qaeda. History has clearly shown that virtually all groups come together in common defense when attacked. If they do enough of these, the western governments will be hard pressed to keep their people from demanding an extermination of all Muslims. That would not be good, but we have already seen many otherwise sane people calling for the destruction of Mecca via atomic weapons.
We are moving in that direction, although I don't think the United States will ever go as far as that. But if they use nukes, all bets are off.
It's hard for me to see what the point of Al Qaeda is, other than evil devotion to radical Islamic hegemony. In other words, what's their endgame?
They've opened war on so many fronts, they seem unfocused, only striking wherever they see the defenseless.
What shows a huge "misjudgement" is claiming Al Qaeda had any part in the attack given that there is no evidence which would indicate a link between the attacks and Al Qaeda.
