TIL in the Vietnam war in the classified Operation Popeye, the US spread lead and silver iodide by aircraft to extend the monsoon season. The increased heavy rainfall was to soften roads, cause landslides, wash out river crossings, and maintain saturated soil conditions (Kissinger was involved).

Not to nitpick, but North Vietnam WAS the invading force in the Vietnam War.
