Hi
The Sword and the Dollar is a good accounting of US and US backed attrocities during the Cold war as a way of maintaining imperialism. It pays close attention to parts of South America, from what I remember.
Honestly it was a difficult read due to how graphic and detailed the eye witness reports are. But I still consider it a must read especially for US comrades.
Also Parenti usually has lectures he gave at universities on his books uploaded to YouTube by various people. So if you are unsure on a book you can listen to him give an about one hour summary of it by just searching the name on YouTube
They ran out of Kaubars right when I went to check out, was the last of the Kufiyas, gonna have to wait cause they sold out of everything quick which itself is awesome that there is this much demand for them
