Last I checked, there were over 2100 mosques in the US. Most are hardened.

I live around the corner from a ‘hardened mosque’. I’m sure the resources of the USA can flatten them without collateral damage.
Good thing dozer blades are too.
While I don’t agree we need a mass extermination, we do need to throw all of them back in their middle east nest of vipers, destroy all who resist or assist them, and tell them in no uncertain terms that if the ever come out again, they will get to see their 13th prophet.
