The first step in this process should be for the United States to transition from being the frontline defense of NATO countries to a supporting role. European democracies in the 1950s were poor and destitute. No more. Germany, for example, has the world’s fourth-largest economy. It is more than financially capable of providing the bulk of its own security. U.S. troops, meanwhile, should be redeployed to home bases where they can focus on defending America’s borders and global interests.
