I guess so if you don’t care about preserving buildings, bridges, roads, airports, and other infrastructure.
Remember; in the civil war scenario we would also be living in the same places (somewhat) we just destroyed afterward. I just can’t see us destroying the tall buildings in NYC or other cities if we had another way to win; albeit taking longer but with less loss of life.
Maybe I’m dreaming but let’s say the right won; would those who fought for the left have to concede or leave? What if the left won? Would we have to concede or leave?
Well actually I’d rather lose that stuff than sell my soul.
And what you’re proposing wouldn’t shrink the left. It would grow it, including among places where “we” thought we were prevailing.
If the left won, they’d establish “re-education” centers, from which very few conservatives would ever return. Take that to the bank.
