星期三是美国总统奥巴马上任的第100天。100天期间，奥巴马总统着手应对了一系列需要解决的问题–采取措施扭转全球经济危机，改变美国在伊拉克和阿富汗战争中的做法，修改拘留和审讯政策，并且致力于改善美国与世界各国的关系。
在总统竞选诺言“改变”的驱动下，奥巴马总统上任数周之内就改变了他的前任布什总统的若干政策。奥巴马作为总统最先采取的行动之一，就是承诺在一年之内将关闭有争议的美军在古巴关塔那摩湾的监狱。
关于伊拉克战争，总统奥巴马设定的最后期限是2010年8月底之前将大部分美军撤离伊拉克。他还宣布了一项针对阿富汗和巴基斯坦的新战略，保证有更多的美军部队参与训练阿富汗的安全部队。
与此同时，房屋和信贷市场的下滑以及失业剧增，奥巴马总统寻求国会批准巨额资金拯救陷于危机的银行系统。他还推动了大规模经济刺激计划，尽管共和党强烈反对有关立法。
Wednesday (April 29th) marks U.S. President Barack Obama’s 100th day in office. In that time, Mr. Obama has tackled a range of issues — taking steps to reverse the global economic crisis, changing the U.S. approach to the wars in Iraq and Afghanistan, modifying detention and interrogation policies and working to improve U.S relations with the rest of the world.
Driven by a campaign message of “change,” Mr. Obama reversed a number of policies of his predecessor, George W. Bush, within his first few weeks. In one of his first acts as president, Mr. Obama pledged to close the controversial U.S. military prison at Guantanamo Bay, Cuba, within a year.
For the Iraq war, President Obama set a deadline of August 2010 for most U.S. troops to leave the country. He also announced a new strategy for Afghanistan and Pakistan, pledging more U.S. forces to train the Afghan security forces.
Meanwhile, as the housing and credit markets slumped and unemployment soared, Mr. Obama turned to Congress for billions of dollars to rescue failing banks. He also pushed through a massive stimulus package, despite strong Republican opposition to the legislation.
