I wasn't talking about just the buildings.  Mass attendance in Europe had declined by half.  It wasn't just the buildings in ruin, it was literally the Church itself.  Americans can't seem to grasp that the Vatican paid a big price in Europe for it's tepid response to facism before and during WWII.  People became cultural Catholics/secularists instead of practicing Catholics. The Churches were well on their way to becoming the mostly empty museums they are now.  Vatican II was probably too little too late to save Europe.  It worked better elsewhere....at least for a time.  

The USCCB is repeating the Vatican's WWII mistake in not speaking out forcefully against Trump and his brand of authoritarianism. If this continues,  will see similar results in the US Church when Latinos take the same exit door as so many whites already have.  The rot not changed by Vatican II was inherent clerical authoritarianism.  Until that changes the exodus will continue.
