A bullet to the head? I can’t see that bringing anyone to Christianity and worse, how would that separate Christians from Muslims when we are using the same “convert or die” mindset of the Muslim? Islam spreads by the sword, Christianity spreads from heart to heart through love and peace.
Europe is beyond help, and we are moving in the same direction. We will not be able to fix someone else while we remain broken ourselves.
Like I said, Charles Martel did the exact same thing for the pagans he defeated in battle, and he WAS a Christian. If he can do that with Europe being populated by firm believing Christians, I see no reason why it can’t be done here. And besides, Jesus never said “let bygones be bygones”, he said “go and spread the gospel to the four corners of the world” which isn’t much different than spreading it by the sword. Unless you want us to just do it like Jimmy Carter did with the Shah of Iran?
