I generally agree with everything you’re saying, and I suspect from listening to Mike Benz a lot, he would too. What you’re saying is totally compatible with what he’s saying.

I think what he is essentially suggesting is that American Foreign Policy has arguably been a form of theft, making things cheaper for Americans (and the West) for the last 80 years. In the long run, free markets and cooperation makes everything cheaper for everyone. In the short term, theft can make it a lot cheaper for some at the expense of others. And ending a theft program can make it more expensive in the short term for those accustomed to being beneficiaries of theft. He’s essentially warning there could be unexpected consequences to stopping the theft.

I don’t think he’s advocating for the foreign policy of the last 80 years, just suggesting that it may have benefitted Americans (albeit unjustly and certainly unequally). It’s still a violation of property rights and certainly democratic freedoms, so it’s wrong. And I think he would agree.

TLDR this subset of Mike Benz’s thinking is not fully representative of his views.
