It would be great if Tom could do a lecture on this. I have some friends and family who are ardent neo-cons and I tried arguing with them, but what I realized is that their stance actually has a particular philosophy, rather than simply a misguided view of the world. The main argument from them is “if the US doesn’t dominate the world, someone else will, and I don’t want the Chinese or Russians to have this kind of control and influence”. I’m not yet wise enough to be able to argue this as I am new to Libertarian principles, and I’m sure Tom could knock this argument down.
