How a nation with totalitarian form of government became an ally of the US?

A nation with a totalitarian government may align with the United States due to strategic interests, such as mutual threats or economic benefits. The Cold War era exemplified this, where the U.S. formed alliances with authoritarian regimes to counter the influence of communism. Additionally, pragmatic considerations, such as access to resources or geopolitical positioning, can lead to cooperation despite ideological differences. Such alliances often prioritize stability and security over democratic values.
