No, we cannot come back from this. The die is cast. There is no putting the genii back in the bottle. True that Europe is much worse, but that only means their collapse will come faster. Ours is still coming and there is no stopping it.
Of course it can be stopped - but Americans would have to be inconvenienced with children to do so. Choices have consequences.
After the fall of France in 1940:
“Today when France is in the grips of true misfortune, there is no more place for lies and fantasies. Too few babies, too few weapons, too few allies—these are the causes of our defeat. We tried to make things easy for ourselves, and today we face misfortune.”
Philippe Pétain
