Both libertarians and conservatives want to keep America safe. We differ on how best to do that. Most libertarians believe our attempts to create or support democracy around the world have made us new enemies, and done harm as well as good. We want less military spending.
Some conservatives respond to that by calling us isolationists, but we're not. I want to participate in the world; I just don't want to run it. I'm glad Americans trade with other countries -- trade both goods and people. It's great we sell foreigners our music, movies, ideas, etc. And through dealing with them, we also learn from what they do best.
On my TV show this week, former U.S. ambassador to the U.N. John Bolton will tell me why my libertarian skepticism about the importance of a "strong military presence" is "completely irrelevant to foreign policy decision-making."
Bolton thinks it's dangerous and provocative for America to appear militarily weak. He supported the Iraq War and says that if Iran were close to getting nuclear weapons, the U.S should attack. "I will go to my grave trying to prevent every new country we can find from getting nuclear weapons," because if they do, "it's going to be a very dangerous world."
He criticizes Presidents Barack Obama's and George W. Bush's failed attempts at negotiation with Iran, "negotiation based on the delusion from the get-go that Iran was ever serious about potentially giving up its nuclear weapon program."
That kind of talk makes Bolton sound like a hard-headed realist. Who wants to be naive like Bush or Obama? But hawks like Bolton ignore parts of reality, too.
They are quick and correct to point out the danger of Iran going nuclear. They are not as quick to talk about the fact that Iran has a population three times the size of Iraq's -- and the Iraq War wasn't as smooth or short as then-Vice President Dick Cheney and others assured us it would be.
If it's realistic to acknowledge that America has dangerous enemies, it's also realistic to acknowledge that going to war is not always worth the loss of money and lives, and that it makes new enemies. War, like most government plans, tends not to work out as well as planners hoped.
I asked Bolton if he thought the Vietnam War was a good intervention. "Obviously, the way it played out, it was not," he said, but, "it's always easy after the fact to second-guess."
