General George Casey, the Army’s top officer, is concerned that diversity will become a casualty of the Fort Hood tragedy.

The religious beliefs of suspect Major Nidal Malik Hasan, a Muslim Army psychiatrist, have led to speculation about motive in the shooting rampage that killed 13 people.

“I’m concerned that this increased speculation could cause a backlash against some of our Muslim soldiers. And I’ve asked our Army leaders to be on the lookout for that,” Casey told CNN’s “State of the Union.”

Asked on NBC’s “Meet the Press” whether Muslim soldiers are conflicted in fighting wars in Muslim countries like Afghanistan and Iraq, Casey said: “I think that’s something that we have to look at on an individual basis. But I think we as an Army have to be broad enough to bring in people from all walks of life.”

The bottom line is the military benefits from diversity, he said.

“Our diversity, not only in our Army, but in our country, is a strength. And as horrific as this tragedy was, if our diversity becomes a casualty, I think that’s worse,” Casey said.

President Barack Obama also mentioned military diversity in his Saturday radio address which was focused on Fort Hood.

Veterans Day is a chance to honor Americans who served in battlefields all over the world, Obama said. “They are Christians and Muslims, Jews and Hindus and nonbelievers.”

“They reflect the diversity that makes this America. But what they share is a patriotism like no other,” Obama said.
