imperial

Any successful nation rediscovers imperialism eventually. Nazis can be called the least imperialistic because their attachment to blood purity turns everyone into their natural enemy and reduces their recruitment pool.

Of course, in the real world any nationalist state would switch to fascism after some success. Because people only want what is rare. When freedom is rare, liberty factions rise. When a nation faces extinction, nationalist factions arise. Remove the scarcity, and people will forget it exists.

Communism can be said to be the most imperialistic because it sees the whole world as their recruits and all countries as temporally occupied territories.
