Tough talk on Pakistan from U.S. Democrat Obama

By Steve Holland

WASHINGTON (Reuters) - Democratic presidential candidate Sen. Barack Obama said on Wednesday the United States must be willing to strike al Qaeda targets inside Pakistan, adopting a tough tone after a chief rival accused him of naiveté in foreign policy.

Obama's stance comes amid debate in Washington over what to do about a resurgent al Qaeda and Taliban in areas of northwest Pakistan that President Pervez Musharraf has been unable to control, and concerns that new recruits are being trained there for a Sept. 11-style attack against the United States.

Obama said if elected in November 2008 he would be willing to attack inside Pakistan with or without approval from the Pakistani government, a move that would likely cause anxiety in the already troubled region.

"If we have actionable intelligence about high-value terrorist targets and President Musharraf won't act, we will," Obama said.

The Illinois Democrat is trying to convince Americans he has the foreign policy heft to be president after a rival candidate, New York Democratic Sen. Hillary Clinton, questioned his readiness to be commander in chief.

Clinton last week labeled Obama naive for saying he would be willing to meet the leaders of Iran, Cuba, Syria, North Korea and Venezuela without preconditions in his first year in office.

A poll by The Wall Street Journal and NBC News said Clinton has widened her lead over Obama, going up to 43 percent in July from 39 percent in June. Obama tallied 22 percent, down from 25 percent in June.

Those polled cited Clinton's experience and competence highest among her positive attributes.
