Had Allende been allowed to have his way, Chile would probably be like Cuba today, poor, miserable, and enslaved, rather than the richest and most stable country in the region. Chile under Allende also would have been another foothold for the Soviets in the Western hemisphere.

Castro didn't come out as a totalitarian communist on the morning after the revolution. He first methodically solidified his power and only showed his true colors when he knew his position was safe. There's every reason to believe that Allende was following the same playbook.
