The correct answer is - the new leader quickly became a military dictator.
After the overthrow of President Guzman, he and his family fled through multiple countries, and eventually his family fell apart, with him ending up as an alcoholic, spending his last years of life in Mexico.
Carlos Castillo Armas was the next Guatemalan president. He was installed into that position by the United States. Castillo quickly became a military dictator. He questioned, tortured, killed, tens of thousands of people. Was implementing terrible damaging laws that set the country backwards, so no wonder that most of the population disliked him, and his reign quickly came to an end.
