WASHINGTON U.S. President Barack Obama expects NATO to announce on Friday a "significant number" of fresh troops for Afghanistan, an administration official said.
Obama will stress in a speech on his new strategy on Tuesday that the U.S. commitment in Afghanistan is not open-ended, the official told reporters in a briefing before the speech.
The president has directed that all U.S. combat forces partner with Afghan security forces for training purposes.
The official discounted criticism that setting a timeframe for the withdrawal of U.S. forces might prompt Taliban fighters to lie low until U.S. troops leave. "If the Taliban thinks they can wait us out, I think that they are misjudging the president's approach," the U.S. official said.
