The entire premise is ridiculous.
Since when do we get a phone call or a written invitation to Al Qaeda gatherings? Is there any doubt that after the huge number of these people that we have killed, that an incredible amount of effort goes into keeping a meeting like this secret?
Would it have been sweet if our intelligence folks had found out about this and droned these people or dropped a JDAM on them? No doubt. Does some fault attach because that doesn't happen? Uhhhh. No.
I also have no doubt that if we had droned them and there had been collateral damage or a traitorous US citizen found in the smoking charred remains, the Admiral and Whirlytard would be bleating about innocents being killed and constitutional rights being violated.
It's more idiocy from the Admiral with support from Whirlytard, his partner in stupidity. Only the mouthbreathers on the right would take the opportunity to criticize our commander-in-chief because Al Qaeda managed to hold a meeting without getting their shit scattered to the wind. Classic Obama Derangement Syndrome.
