I thought you might be interested in these videos. Ben Livingston (interviewed in these videos by Alex Jones) was involved in secret US goverment operations to turn the weather systems over VietNam into weapons systems used against the battlefield mobility of the NVA. Specifically, he turned rain storms, via weather modification through cloud seeding, into hellish monsoons that washed out the Ho Chi Minh trail and many of its pathways and bridges thereby making it more difficult for the NVA to move supplies.
To the on the ground GI, these videos might explain having to smoke all those soggy cigarettes while soaked to the bone and covered with mud. Dave
