What American-Vietnam war and American-Afganistan war had in common was counterinsurgency of the opposing forces embedded with local population (VietCong embedded with local south Vietnamese villagers; Taliban embedded with Afghan villagers). This broke the war for Americans. (If we are pedantic we can observe a similar situation in the second American-Iraqi war with similar outcome for Americans) This situation is not present in the Russo-Ukrainian war.
