Despite US offers of more help, only two FBI agents are present in Malaysia's capital Kuala Lumpur, where local officials are scouring the records of dozens of passengers and two pilots for clues into the jetliner's disappearance on March 8.
Speaking anonymously, American officials told The New York Times they believed Malaysian authorities didn't want to look like they can't handle things on their own.

It could also have something to do with historically chilly relations between the United States and Malaysia, which were incredibly strained while Mahathir bin Mohamad served as Malaysia's prime minister from 1981 to 2003.

However, a spokesman for the US Seventh Fleet said the two governments have been cooperating on the latest efforts. "You have the Malaysian government, the US government and other governments using military information, civilian satellite information," Cmdr.

That could be in part due to the current prime minister, Najib Razak. He pointed out that Malaysia had shared its sensitive military radar data with other countries in an effort to locate the missing plane. "We have put our national security second to the search for the missing plane," he said.
