TLDR: see title

A lot of discussion has been made on this subreddit as well as many other places about the decline of America and western civilization in general. Between low fertility rates, cultural marxism, mass immigration legal and illegal, its obvious that western civilization is going down. Just like the Roman Empire. But the question is what will that actually look like in this day and age?

Will it be a formal invasion by other countries? Will it be collapse from within? Or will the tide of immigration turn the west into extensions of the immigrants countries of origin?

Lessons Learned: Enjoy the decline
