Two examples of "what is Jimmy Carter guilty of?"
1. Guatemala:
During Carter's administration the US, via the CIA, continued to interfere in Guatemala's internal affairs, funding the activities of an elite Guatemalan army unit known as "Unit G2" which carried out politically motivated murders and assassinations. Officers of this unit were secretly paid by the CIA and worked out of the US Embassy and various safe houses belonging to the CIA. This had been going on since the 1950s but Carter did not put a stop to it.
According to Amnesty International, between 1978 and the mid 1980s, Unit G2 and another unit known as "Archivo" were responsible for the deaths of more than 110,000 Guatemalan civilians.
2. Turkey:
The US directly supported the 1980 coup in Turkey through which the military siezed power. During the coup and in the months after, at least 250,000 people were arrested. At least 50 were executed, thousands were brutally tortured, and thousands of the prisoners went missing, never to be heard from again. This violent repression of the Turkish people was supported by Carter's administration, and the military regime in Turkey went on to torture and kill thousands more people during the 1980s.
