Go read The Theology of American Empire at The Smirking Chimp. It’s by Ira Chernus, a professor of religious studies at the University of Colorado at Boulder. We should all listen to him, but we won’t. Sample:

The bipartisan consensus on U.S. foreign policy calls for us to be powerful enough to dominate them. But every step we take to dominate only antagonizes more people and makes some of them really want to harm us. As long as we keep on this self-defeating road, we are not a national security state. We are a national insecurity state.

So, we need to redefine national security in a way that meets people’s need for a second value that so many of us share: moral certainty. This involves a faith in some rock-bottom kind of goodness in the world, which many Americans believe has a special home here in the United States.

There is a special kind of goodness, rooted in a special kind of theology, that does have an old and honored home here — the goodness of nonviolence. There have always been Christians who were certain that the only moral way to treat others, even enemies, is with love, not violence. They knew it because Jesus said it, right there in the Bible. In 19th-century America, the abolitionists and Thoreau turned the theology of nonviolence into a homegrown strategy for political change.

Martin Luther King, Jr. took this strategy a crucial step further. He preached that it’s the government’s role to help bring all people together in what he called “the beloved community” (something very much like what the Social Gospel called the Kingdom of God). Every government policy should promote “the mutually cooperative and voluntary venture of man to assume a semblance of responsibility for his brother [and sister]” — the responsibility to help every person fulfill their God-given potential.
