Not being willing any longer to be manipulated is not succumbing to isolationism. Wondering whether the United States can afford another liability is not mindless nationalism. Questioning whether America can afford the status quo here and abroad is not heresy. Assuming we can borrow our way out of any inconvenience is largely over.
What helped elect Trump was a collective weariness with demands put on a country $20 trillion in debt. America is currently running a $57 billion a month trade deficit.
The poverty of inner-city Detroit, or rural Central California, or West Virginia does not suggest an endlessly opulent nation, at least as a visitor might conclude from visiting Manhattan, Chevy Chase, or Presidio Heights.
NATO was designed to protect Western Europeans from Soviet expansionism and to allay fears of traditional Russian nationalism. It transmogrified into a vital Western alliance that might use collective deterrence and action to preserve shared democratic values.
But if a distant United States is to continue anchoring such a key defensive league, then surely its front-line member states of a prosperous Europe must meet or exceed their own freely agreed upon levels of defense spending.
Instead, until recently, most did not.
The unspoken premise for such nullification was that the United States needs NATO more than the NATO states in Europe need the United States. Or given that America is so big and powerful a patron, surely it could always afford to subsidize an errant client.
Mexico assumed that a rich neighbor could, in perpetuity, serve as a refuge of last resort for its impoverished citizens, thereby providing a safety valve and precluding any need for its own internal reform.
The United States was supposedly so affluent that it could both offer entitlements to illegal aliens and, given such aid, not care whether many of them sent $60 billion back home (what is a mere $60 billion out of a multi-trillion dollar economy?) to Central American and Mexico.
When occasionally the United States recoiled a bit, Mexico could always accuse an essentially open-border America of being restrictionist and xenophobic. One wonders how exactly would Mexico’s hostility be expressed—by vows not to receive remittances, or to demand repatriation of its lost citizens, or unilaterally to leave NAFTA, or to elect a nationalist president who would build a wall?
