WASHINGTON, July 22 (Xinhuanet) -- The US government has not done enough to improve the country's security status to prevent future terror attacks, a leading member of the Sept.11 commission said Friday.

    Speaking on the "Today" show of the National Broadcasting Company, Lee Hamilton, vice chairman of the independent investigation body, said the Bush administration has not fully adopted a host of recommendations that his panel proposed one year ago.

    The recent bombings in London have made the issue even more pressing, he said.

    "A lot of things have not been done," Hamilton said, noting that the country has yet come up with a unified terror suspect watch list, although it should have been worked out several years ago.

    The recent incidents in London showed that the United States isnow facing a smarter enemy who is getting more used to exploit the weakness of western societies, he noted.

    However, what the US government has done in security affairs so far can only be graded as "mixed," with both disappointments and successes, said Hamilton.

    Although the government has created a new position of the national intelligence director to centralize information-gathering from various agencies, the change remained largely superficial rather than practical, he said.

    The Sept.11 commission, founded in 2002, was assigned to thoroughly investigate the country's security loopholes before and after the terror attacks of Sept.11, 2001, and to make recommendations on prevention measures.

    In its final investigation report released last July, the commission put forward 37 recommendations to the government. Enditem
