问答题 Born in Hawaii, raised for some of his childhood in Indonesia, Barack Obama has since his election wanted to be known as America's first "Pacific President." Until recently, he has not done much to earn the title. That, Mr. Obama declares, is now changing. Allies in Asia have complained about only intermittent American attention to their region. But in a speech to Australia's parliament on November 17th, Mr. Obama announced that America is back. "Let there be no doubt: in the Asia-Pacific in the 21st century, the United States of America is all in." It was, he said, a "deliberate and strategic decision": America was "here to stay." Senior administration officials back up the president. They talk of a new "pivot" in foreign policy towards Asia. They say that much of Mr. Obama's first term has been spent dealing with "inherited" issues, many of them linked to George Bush's war on terror. But America is now out of Iraq, and there is a deadline to free itself from Afghanistan. So Asia is coming more into focus. Of course, old problems, such as Iran, can rapidly force themselves back to the top of the president's agenda, and old European allies still command the most trust. But insiders hope that the Pacific will be the new strategic focus.
