"Operation Popeye (Project Controlled Weather Popeye / Motorpool / Intermediary-Compatriot) was a highly classified weather modification program in Southeast Asia during 1967–1972. The cloud seeding operation during the Vietnam War ran from March 20, 1967 until July 5, 1972 in an attempt to extend the monsoon season." [1]

"After World War II, the U.S. military bombed dams in North Korea and North Vietnam to destroy the communist governments’ electricity and irrigation infrastructure. This was, until the Iran-Iraq War, the final occurrence of such soggy tactics. In 1977 the Geneva Conventions specifically outlawed the targeting of water infrastructure in wartime." [2]
