President Donald Trump has always had contradictions in his "tough guy" national security policy. For starters, he has proposed a nearly 10 percent increase in defense spending, but also claims that his demands for U.S. allies to spend more on defense are producing results. And during his campaign, he alluded to the need to stay out of unneeded wars. If allies pay more and the United States stays out of pointless brushfire wars, the U.S. government could seemingly spend less, not more, on defense.
However, allied defense spending is probably not going to increase that much. Our wealthy allies have long allowed the United States to spend most of the money on security, so that they can use their money to compete with U.S. commercial interests on the world market without fully opening their markets to American products and services. Trump is right to pressure the allies to do more, but they really won't unless the United States tells them the y are mostly on their own to provide security.
