During the chaotic days after the Sept. 11, 2001, terrorist attacks, Basim Elkarra was passing by an Islamic school in Sacramento when he did a double-take: The windows were covered with thousands of origami cranes - peace symbols that had been created and donated by Japanese Americans.

Amid the anger and suspicions being aimed at Muslims at that time, the show of support "was a powerful symbol that no one will ever forget," said Elkarra, a Muslim American community leader in California.

It was also the beginning of a bond between the two groups that has intensified as House Homeland Security Committee Chairman Peter T. King (R-N.Y.) prepares to launch a series of controversial hearings Thursday on radical Islam in the United States.

Spurred by memories of the World War II-era roundup and internment of 110,000 of their own people, Japanese Americans - especially those on the West Coast - have been among the most vocal and passionate supporters of embattled Muslims. They've rallied public support against hate crimes at mosques, signed on to legal briefs opposing the government's indefinite detention of Muslims, organized cross-cultural trips to the Manzanar internment camp memorial near the Sierra Nevada mountains in California, and held "Bridging Communities" workshops in Islamic schools and on college campuses.

Last week, Rep. Michael M. Honda (D-Calif.), who as a child spent several wartime years living behind barbed wire at Camp Amache in southeastern Colorado, denounced King's hearings as "something similarly sinister."

"Rep. King's intent seems clear: To cast suspicion upon all Muslim Americans and to stoke the fires of anti-Muslim prejudice and Islamophobia," Honda wrote in an op-ed published by the San Francisco Chronicle.

King has defended the hearings by arguing that the Muslim American community has not always been cooperative with the FBI and other law enforcement authorities in countering the growth of radical Islam. And he rejects accusations that he is demonizing Muslims and ignoring threats from other extremists.

In an interview Sunday on CNN, King noted that U.S. Attorney General Eric H. Holder Jr. "is not saying he's staying awake at night because of what's coming from antiabortion demonstrators or coming from environmental extremists or from neo-Nazis. It's the radicalization right now in the Muslim community."

But Honda compared King's position not only to the wartime roundup of the Japanese, but also to the anti-Communist hearings staged by Sen. Joseph McCarthy in the 1950s.

"I'll be damned if I'm going to stay quiet and not say something," Honda said in an interview this week. "We have to show people that as Americans, we're not going to put up with this kind of nonsense."

Although the youngest who were interned are in their late 60s, Japanese Americans remember what it means to be targeted during wartime because of their nationality.

After the Japanese attacked Pearl Harbor in December 1941, President Franklin D. Roosevelt ordered that all ethnic Japanese along the Pacific Coast be sent to one of 10 isolated internment camps in seven states. Of those imprisoned, 62 percent were second- or third-generation Japanese Americans born in the United States. Most lost their property to the government.
