With a POD after 1945, come up with a scenario where a rogue state akin to North Korea in it's mixture of batshit insanity, oppressive government, and willingness to threathen it's neighbors with war is around in Latin America. Bonus points if said Latin American dictatorship has it's own nuclear weapons as well.
Note: Said regime does not need to be following some distortion of communism like OTL's DPRK, so crazy far-right ultra-nationalism can do for this rogue state's ideology
