He’s not talking about within our borders, but outside them.
He's not, but I am. The federal government's growth in power and size is bankrupting the states and destroying their sovereignty. It is federal imperialism.
But his point is not entirely off the mark. I don't think it has to be all or nothing like most of the posts suggest. We can and should meet our obligations abroad and at home in a fiscally responsible manner.
He is right that if we go broke there will be nothing left for our military to defend.
