If it walks like a duck and talks like a duck...

It must be an Iranian. This AP article describes the perpetrators of an attack in Iraq last week that killed five US soldiers:

In perhaps the boldest and most sophisticated attack in four years of warfare, gunmen speaking English, wearing U.S. military uniforms and carrying American weapons abducted four U.S. soldiers last week at the provincial headquarters in the Shiite holy city of Karbala and then shot them to death.
...
The brazen assault, 50 miles south of Baghdad, was conducted by nine to 12 gunmen posing as an American security team, the military confirmed. The attackers traveled in black GMC Suburban vehicles (the type used by U.S. government convoys), had American weapons, wore new U.S. military combat fatigues, and spoke English, according to two senior U.S. military officials as well as Iraqi officials.
...
Iraqi officials said the approaching convoy of black GMC Suburbans was waved through an Iraqi checkpoint at the edge of the city. The Iraqi soldiers believed it to be American because of the type of vehicles, the distinctive camouflage American uniforms and the fact that they spoke English. One Iraqi official said the leader of the assault team was blond, but no other official confirmed that.

Not once does the article suggest that the attackers may actually have BEEN Americans. False-flag ops are nothing new to the US (although I guess this would be "reverse-false-flag"), and of course pretending that they are the work of the enemy-du-jour is standard operating procedure. Still, the military apparently missed the point:

Friday's military statement referred to the attackers as "insurgents," which usually suggests Sunnis.

But an Iraqi official, I'm guessing a Sunni, apparently understood what was happening:

A senior Iraqi military official said the sophistication of the attack led him to believe it was the work of Iranian intelligence agents in conjunction with Iraq's Shiite Mahdi Army militia, which Iran funds, arms and trains.

But of course! Our government wants a war with Iran, so it must have been Iranians! Blond, English-speaking, US uniform-wearing, SUV-driving Iranians.

You see what you want to see, I guess.
