The original title in Russian, Империализм, как высшая стадия капитализма, actually translates to "current highest" or "latest highest," not the last or final. Authors like Cheng Enfu have written works like Five Characteristics of Neoimperialism, analyzing the current characteristics of and contradictions in imperialism today. Moreover, Lenin has still been correct, the global south is rising against imperialism and the global north is declining. The US Empire has become the indusputed hegemon, and as it dies is taking the whole imperialist system propping it up down with it.
