USA - History shows us how great empires like Rome fell, not because they could be beaten militarily, but because they could collapse from within. When the population of that country fails to unify under a single culture, that nation's flag, only social unrest will result. All the enemies of that nation have to do is instigate protests and influence the media to lie to the people and just watch an independent republic melt away.
Yuri Bezmenov, a former KGB agent defected to Canada, gave lecture tours throughout the US in the 1980’s warning Americans of the perils of not responding to the false narratives of radicals advocating socialism and open borders.

Trying to salvage US prosperity from the incompetence of previous President Jimmy Carter, today we see President Trump struggling to restore American prestige after 8 years of the faulty and intentionally destructive policies under President Obama.

This is exactly what the Democrat Party has been doing.
