From Columbus to Castro: The History of the Caribbean, 1492-1969, by Eric Williams (HC, 1970, 576 pages, $3)
This is an ex-lib. book, but you would hardly know it. Writing in 1969. Williams wishes to promote economic integration and political independence in the Caribbean. (He mostly excludes Puerto Rico because he feels it will soon gain statehood.)
"Once all the vestiges of political, economic, cultural and psychological dependence and of racism have been removed from the Caribbean, then and only then can the Caribbean take its true place in Latin America and the New World and put an end to the international wars and inter-regional squabbles which, from Columbus to Castro, have marked the disposition of Adam's will."
(Oh, do I wish it was that easy.)
