So the U.S. will be better off without Europe, without Japan, without Korea?
In what way does our military relationship with any of those countries benefit us anymore? They're all triggers to involve us in a war with Russia and/or China at some point in the future.
I believe we should should have a level of engagement with them but the entire cost structure needs to be reworked at every level. Money, manpower, materiel. Those countries should all be carrying the bulk of the burden required for their defense, without the presence of huge numbers of US troops who serve as cannon fodder to stir the American people to war in the event of an attack.
