Sen. Barack Obama said Friday he would return the country to the more "traditional" foreign policy efforts of past presidents, such as George H.W. Bush, John F. Kennedy and Ronald Reagan. At a town hall event at a local high school gymnasium, Obama praised George H.W. Bush - father of the president - for the way he handled the first Gulf War: with a large coalition and carefully defined objectives. Obama began a six-day bus tour through Pennsylvania, the largest remaining primary prize in the contest with Sen. Hillary Rodham Clinton for the Democratic nomination. Sen. John McCain is the Republican nominee-in-waiting. "The truth is that my foreign policy is actually a return to the traditional bipartisan realistic policy of George Bush's father, of John F. Kennedy, of, in some ways, Ronald Reagan, and it is George Bush that's been naive and it's people like John McCain and, unfortunately, some Democrats that have facilitated him acting in these naive ways that have caused us so much damage in our reputation around the world," he said.
