I find it hard to accept that members of Congress could be so clueless about international sensitivities as to get "blindsided" like this.
Why would this be surprising? This is an institution (the House) which Tom DeLay, a man whose Middle East policy prescriptions are largely dictated by the Left Behind series, ran for years. House Reps especially are elected primarily to focus on domestic issues. I don't know how anyone can be surprised at Congress' ignorance on the most basic issues, much less the nuances of Turkish nationalism and its response to Armenian-American grievances.

To his credit, Reyes, a kindly, thoughtful man who also sits on the Armed Service Committee, does see the undertows drawing the region into chaos.

For example, he knows that the 1,400- year-old split in Islam between Sunnis and Shiites not only fuels the militias and death squads in Iraq, it drives the competition for supremacy across the Middle East between Shiite Iran and Sunni Saudi Arabia.

That’s more than two key Republicans on the Intelligence Committee knew when I interviewed them last summer. Rep. Jo Ann Davis, R-Va., and Terry Everett, R-Ala., both back for another term, were flummoxed by such basic questions, as were several top counterterrorism officials at the FBI.

...

Al Qaeda is what, I asked, Sunni or Shia?

“Al Qaeda, they have both,” Reyes said. “You’re talking about predominately?”

“Sure,” I said, not knowing what else to say.

“Predominantly — probably Shiite,” he ventured.

...

And Hezbollah? I asked him. What are they?

“Hezbollah. Uh, Hezbollah...”

He laughed again, shifting in his seat.

“Why do you ask me these questions at five o’clock? Can I answer in Spanish? Do you speak Spanish?”

“Poquito,” I said—a little.

“Poquito?! “ He laughed again.

“Go ahead,” I said, talk to me about Sunnis and Shia in Spanish.

Reyes: “Well, I, uh....”

...

On the day in 2003 when Iraqi mobs toppled the statue of Saddam Hussein in Baghdad, Bush was said to be unaware of the possibility that a Sunni-Shia civil war could fill the power vacuum, according to a reliable source with good White House connections.

...

Trent Lott, the veteran Republican senator from Mississippi, said only last September that “It’s hard for Americans, all of us, including me, to understand what’s wrong with these people.”

“Why do they kill people of other religions because of religion?” wondered Lott, a member of the Senate Intelligence Committee, after a meeting with Bush.

“Why do they hate the Israelis and despise their right to exist? Why do they hate each other? Why do Sunnis kill Shiites? How do they tell the difference?

“They all look the same to me,” Lott said.
This is not a Congressional problem --- it is, at base, an American problem.
