The coming thing is seeds disguised as seeds. Here's what happens. Ya drop tons and tons of seeds near rivers and water supplies. Seeds that turn into water-sucking plants. Eucalyptus, purple loose strife. Follow that up with air strikes wherein you drop fertilizer. Let the plants grow. THEN, instead of sending in the military, send in people who farm. Together, the people from both sides will have to find a way to defeat the trees and plants. The genius of sheer simplicity.
