Obama complicates the narrative significantly: the very color of his skin, precisely what Al Qaeda mocks, symbolizes America’s willingness to change. That’s exactly what Al Qaeda fears most.

Not a lot. He’s still the POTUS.
You think there’s any colour you could put in charge of Israel that would serve as a bullet proof vest ? No ? Well what’s different here ?
Sadat wasn’t exactly an albino. Everywhere you look in history for jihadists the issue of race and ethnicity hasn’t compared as an issue to the policies that mark leaders as targets.

Either someone’s suggesting the US under Obama is going to change the bipartisan-supported policies that made Clinton a personal assassination target and your country a target for a string of terrorist attacks, or nobody is. Nobody is.

“Zawahiri must not have watched the evisceration of Nader that followed his “Uncle Tom” comment.”

Ya think ?

Meanwhile, the concept of a leader selling out and being a puppet isn’t something new for the jihadi community. Most of the time arab muslims are successfully portrayed as not significantly arably muslimy enough, so I wouldn’t immediately suggest this isn’t going to play well for the intended audience. A demographic that views this whole POTUS role as the worst possible flaw, not the greatest prize as all of you do.

Unless you preiously agreed with putting a whole bunch of other leaders to death for similar reasons, you don’t get to call this a fail on behalf of anyone.
Eric Martin quote his Somali islamist contacts when he made his assessment on behalf of that demographic, did he ?
