In the comments section of an unrelated blogpost, the commenter Matt doggedly argues that the Truman administration deliberately prohibited the European beneficiaries of the Marshall Plan from using American funds to purchase Argentinian wheat in 1948-50. This discrimination, Matt contends, was an attempt to punish Argentina for its nationalist economic policies under Juan Perón. I disputed that a deliberate discrimination occurred at all. But Matt has now cited what I think is conclusive evidence that at least the Economic Cooperation Administration (the administrator of the Marshall Plan funds) did deliberately exclude Argentina, probably under Congressional pressure. The issue is small, a mere footnote on the marginalia of US-Latin American relations very early in the Cold War, but there is a lot of information and argument in there and it’s worth reading the exchange.
