Bush agrees to time 'horizon' on Iraq troop cuts

US President Bush and Iraq's prime minister have agreed to set a "general time horizon" for bringing more US troops home from the war, a dramatic shift from the administration's once-ironclad unwillingness to talk about any kind of deadline or timetable.

The announcement on Friday put Bush in the position of offering to talk with Iraqi leaders about a politically charged issue that he adamantly has refused to discuss with the Democratic-led Congress at home. It also could complicate the presidential campaign arguments of Republican John McCain and Democrat Barack Obama who have staked out starkly opposite stands about the unpopular war.

What's changed? The sharp reduction in violence in Iraq — to the lowest level in four years — has made the country's leaders increasingly confident and more assertive about its sovereignty, giving rise to demands for a specific plan for American forces to leave.

Iraq has leverage because the White House is struggling to salvage negotiations for a long-term agreement covering US military operations there. The White House said its goal is to conclude that deal by the end of this month.

Bush and Iraqi Prime Minister Nouri al-Maliki talked about the stalled negotiations during a secure video conference on Thursday, agreeing "on a common way forward to conclude these negotiations as soon as possible," a White House statement said.

The two leaders agreed that improvements in security should allow for the negotiations "to include a general time horizon for meeting aspirational goals, such as the resumption of Iraqi security control in their cities and provinces and the further reduction of US combat forces from Iraq," the White House said.

Bush repeatedly has vetoed legislation approved by Congress setting deadlines for American troop cutbacks.

Friday's White House statement was intentionally vague and did not specify what kind of timelines were envisioned. That allows Iraqi officials, who are facing elections in the fall, to argue they are not beholden to Washington or willing to tolerate a permanent military presence in Iraq. For Bush, it points the way toward a legal framework for keeping American troops in Iraq after a US mandate expires on December 31.
