The US "did the right thing" by confronting "a gathering threat in Iraq," President Bush said, as a growing number of administration officials defend last year's war as necessary despite the failure so far to find stockpiles of banned weapons. Earlier Thursday, CIA Director George Tenet said his agency provided "an objective assessment" of a brutal dictator who "had the intent and capability" to produce chemical and biological weapons. Defense Secretary Rumsfeld made similar arguments Wednesday before House and Senate panels. Bush is expected to name an independent commission Friday to investigate prewar intelligence lapses, an idea he'd previously opposed.
