Absolutely, and I said as such; but after the US overstretched their forces occupying Iraq, it’s become item #1 at every single NATO summit (only temporarily shadowed by Crimea in the immediate aftermath). Someone will have to pay to rearm a resurgent Iron Curtain (although who knows, maybe Trump will just sell Eastern Europe to his mate Vlad), and someone will have to pay to keep the South China Sea open for business. If governments willing to chip in, have to tweak their constitutions in order to help Uncle Sam, I don’t think any POTUS will complain.
