Blair and Bush clash over their vision for post-war Iraq
US President George W. Bush and Britain's Prime Minister Tony Blair are united in their resolve to effect political change in Iraq, but the strength of their alliance is being tested.
Disagreement over post-Iraq policies will soon force Mr Blair to make some tough decisions. His level of insistence will determine the future of the coalition.
Chief among the potentially damaging issues is the role of the United Nations in Iraq's future, the democratisation of the Middle East and the road map for Arab-Israeli peace.
Mr Blair, who sees himself as a bridge between the US and Europe, is also coming under increasing pressure from his European Union (EU) partners. They want to participate in reconstruction and humanitarian work, but are being mostly frozen out of the process by the US.
The crux of Mr Blair's looming dilemma is the UN. His belief in the world body's value puts him at odds with Mr Bush.
The British leader is said to be seeking a resolution in the UN Security Council to ensure the UN's participation in a post-war administration.
