I have a lot of personal theories how my country can best cope with future geopolitical adjustments. If I were in charge, the first thing I would do would be to close most foreign military bases. We can have the strongest military in the world and have them largely based in the US. I think the US Navy continues to be a good investment, but I would cut back a small amount on intel and other military branches.
forgoing foreign bases and limiting the US military presence to domestic only is such a ludicrous take that I'm willing to bet would have you laughed out of any room discussing defense.
