美国总统布什4日举行新闻发布会，初步阐述了他在第二个任期的施政纲领，其中包括对外继续推进反恐怖战争，对内大幅度改革美国的社会保障和税收系统。据接近白宫的人士透露，布什本人非常希望能将改革后的社会保障体系作为其为后人留下的“最大政绩”。同时，白宫还希望要在未来五年中削减一般的联邦财政赤字的同时，继续推进一个永久性的减税方案。

US President George W Bush has been setting out the agenda for his second term, vowing to reach out to allies while continuing the war on terror.

He told reporters it was a conflict in which every "civilised nation" and every American had a stake.

He also spoke of the need for Middle East peace and said his administration would "achieve our objectives" in Iraq.

The president was heading to his Camp David retreat later on Thursday to consider changes to his administration.

The rare news conference came after Mr Bush held his first cabinet meeting for three months, and probably the last such meeting until his new term starts in January.

There has been much speculation about Mr Bush's forthcoming reshuffle , but the president said he had not yet made any decisions.

"There will be some changes. I don't know what they will be," he said.

He acknowledged disagreements over the invasion of Iraq and said he would reach out to other countries and organisations such as the European Union and Nato.

"Every civilised country also has a stake in the outcome of this war," he said.

"Whatever our past disagreements, we share a common enemy. And we have common duties to protect our peoples."

In an allusion to US allies, such as France and Germany, who opposed the invasion of Iraq, Mr Bush said he had made some "hard decisions" to protect Americans.

"I understand that certain capitals in certain countries, those decisions were not popular," he said.

But he did not signal any changes in foreign policy.

When asked whether he agreed with UK Prime Minister Tony Blair that revitalising the Middle East peace process was the most pressing issue facing the world, the president said:

"I agree with him that the Middle East peace is a very important part of a peaceful world. My hope is that we'll make good progress."

Wrongly informed by a reporter that Palestinian leader Yasser Arafat had died, Mr Bush said: "My first reaction is, God bless his soul.

"And my second reaction is that we will continue to work for a free Palestinian state that's at peace with Israel."

The president won 51% of the popular vote in Tuesday's vote, giving him a stronger mandate than the election of 2000.

Mr Bush said the voters had "set the direction for the next four years".

He said he wanted Congress to reform social security and the tax system.

"I've earned capital in this election and I'm going to spend it," Mr Bush said.

There have been reports that Attorney General John Ashcroft and Homeland Security Secretary Tom Ridge both plan to resign for personal reasons.

Defence Secretary Donald Rumsfeld is among those who are unlikely to last the full term. He may stay for another year or so if he wants to.

Secretary of State Colin Powell is expected to go, but not everyone is convinced he wants to.

There is speculation he might be replaced by the recently appointed US ambassador to the UN, John Danforth.

National security adviser Condoleezza Rice has said in the past that she wants to return to her university career, but she is close to the president and is thought by some to harbour presidential ambitions.

Vice-President Dick Cheney has suggested the administration now has a mandate for a range of conservative social and economic policies.

These are likely to include issues ranging from tax reform to abortion and same-sex marriage.

President Bush will get the chance to appoint conservative justices to the Supreme Court if seats become vacant, which could have an impact far beyond his presidency.

The powerful nine-member court is able to take final decisions on issues ranging from the result of a presidential election to a woman's right to have an abortion.
