For the most part - internally the U.S. doesn't function as one nation nor as separate countries that can close their borders. Our political makeup will make social distancing on the national scale nearly impossible. In areas it isn't bad in yet - they will be lax on it. In areas it's hard hit they will go more extreme. The problem is without us working in unison this is going to be one very prolonged battle where we constantly export the virus back to places that recovered from it. So on some level maybe he's right that the best option for the U.S. may be to just tough it out because the will isn't there for all states and counties and cities to work together and all make the necessary sacrifices on this.
It's almost as if we are in a real life prisoner's dilemma and aren't sticking to the smart play.
