Blair is the youngest prime minister in Britain since 18 12, and the first prime minister to be re-elected for three terms as the leader of the Labour Party. He made great achievements in internal affairs, and created the longest lasting economic prosperity in Britain after World War II and other amazing achievements. He could have ended his third term with dignity in 2009 and gone down in history with excellent results. However, due to the big mistake in the Iraq war, the general trend has gone, and I have to step down two years early.

Blair's "bad record" in the Iraq war is hard to be forgiven by most British people and history. First, the Iraq war is the most unpopular war launched by the United States after the Cold War. President Bush is the first responsible person. But in Bush's last meeting with Blair before the war, the latter made every effort to fight the main battle, prompting Bush to make up his final determination to go to war. Apart from the United States, Britain sent troops to the war the most. It can be said that Blair is the second person responsible for the Iraq war. Secondly, in order to gain the support of the British Parliament and the public, Blair actually fabricated an excuse that Iraq "may develop nuclear weapons within 45 days". It turned out to be a big lie, and Blair's credibility was destroyed. Thirdly, the Iraq war made Britain pay a heavy price, which not only caused great loss of people and property, but also made Britain a key target of international terrorist attacks, such as the "7 7" London underground bombings. At the same time, Blair unconditionally followed Bush, making him a "running dog" and "follower" of Bush, and also affecting Britain's international image. Fourth, the Iraq war is wrong, which has been recognized by the world and is also the mainstream view of American and British public opinion. But Blair, like Bush, never admits his mistake and is determined to "carry the Iraq war to the end".

Blair's actions in the Iraq war not only made him lose the hearts of the people, but also seriously dragged down the British Labor Party. In a recent opinion poll, the support rate of the Labour Party was only 27%, a record low. In the recent local elections, the Labour Party suffered another crushing defeat. David Cameron, leader of the British Conservative Party, sarcastically said that the Labour government has become a "living and dead government" because of Blair's "love of war", and it is difficult for the Labour Party to win the next national election in Britain. In this case, Blair has no choice but to hang the crown.

Some analysts pointed out that Blair's resignation time was carefully chosen. Northern Ireland's local self-government was sworn in in Belfast on the 8th, and leaders of once opposing political factions formed a government, thus Northern Ireland entered a new era of power sharing. Blair chose to resign after this landmark progress, aiming at silently telling his "retirement" in the long-term promotion of the peace process in Northern Ireland, which not only brought a satisfactory end to his political career, but also increased the support rate for the Labour Party. The Labour Party did not perform well in the recent local elections, and Blair handed over power smoothly in order to regain the support rate of the Labour Party.
