President Bush, speaking in Israel this week, gave a great speech that in my view really drew some solid distinctions between Obama and the Republican view of foreign policy:
"...We believe that targeting innocent lives to achieve political objectives is always and everywhere wrong. So we stand together against terror and extremism, and we will never let down our guard or lose our resolve.The fight against terror and extremism is the defining challenge of our time. It is more than a clash of arms. It is a clash of visions, a great ideological struggle. On the one side are those who defend the ideals of justice and dignity with the power of reason and truth. On the other side are those who pursue a narrow vision of cruelty and control by committing murder, inciting fear, and spreading lies. This struggle is waged with the technology of the 21st century, but at its core it is an ancient battle between good and evil.... And that is why the founding charter of Hamas calls for the "elimination" of Israel. And that is why the followers of Hezbollah chant "Death to Israel, Death to America!" That is why Osama bin Laden teaches that "the killing of Jews and Americans is one of the biggest duties." And that is why the president of Iran dreams of returning the Middle East to the Middle Ages and calls for Israel to be wiped off the map. There are good and decent people who cannot fathom the darkness in these men and try to explain away their words. It's natural, but it is deadly wrong. As witnesses to evil in the past, we carry a solemn responsibility to take these words seriously. Jews and Americans have seen the consequences of disregarding the words of leaders who espouse hatred. And that is a mistake the world must not repeat in the 21st century. Some seem to believe that we should negotiate with the terrorists and radicals, as if some ingenious argument will persuade them they have been wrong all along. We have heard this foolish delusion before. As Nazi tanks crossed into Poland in 1939, an American senator declared: "Lord, if I could only have talked to Hitler, all this might have been avoided." We have an obligation to call this what it is — the false comfort of appeasement, which has been repeatedly discredited by history. Some people suggest if the United States would just break ties with Israel, all our problems in the Middle East would go away. This is a tired argument that buys into the propaganda of the enemies of peace, and America utterly rejects it..."
Compare that speech to Obama calling our relationship with Israel a "constant sore" and it's not difficult to see why Hamas endorses one candidate over another.
