听力原文： President George W. Bush insisted the Iraq war could still be won and dismissed mounting calls for a change in strategy as US lawmakers voted again for troop withdrawals.

Bush struck a defiant tone Thursday, insisting on his authority to run the war despite a report from his ad- ministration showing the Iraqi government was making only paltry progress and growing anxiety over the war from fellow Republicans.

Bush frequently invoked Al-Qaeda, warning the withdrawal of 160,000 US troops in the country would mean "surrendering the future of Iraq to Al-Qaeda."

The House of Representatives answered Bush with a vote to withdraw most combat troops by April, as Democratic leaders blasted the president's handling of the war. The House voted by 223 votes to 201 to pass the measure, but the Republican coalition stayed intact: only four party members voted with the Democrats.

What is Bush's reaction towards US troop withdrals ?

A．Support.

B．Objection.

C．Neutrality.

D．Unclear.
