There are large tracts of forest in Cambodia, despite the deforestation campaigns waged on Cambodia during the American(vietnam)war.

Vietnam: Phosphates, coal, manganese, bauxite, chromate, offshore oil, gas deposits, forests, and hydropower
To destroy the forests; by 1969 the Army was transitioning to ROME Plows; bull dozers equipped with angled blades to mow down the forests.
Vietnam wasn't affected; SOUTH Vietnam was affected. NORTH Vietnam may not have been sprayed, but parts of the Ho Chi Minh Trail in Cambodia/Laos may have caught some of it. SOUTH Vietnam is where the vegetation was...that's were the enemy was hiding...that's where the forests and jungles had to be destroyed...to uncover the enemy...and keep him from remaining hidden. If the enemy was hiding and using forests and jungles in NORTH Vietnam...the US simply bombed the heck out of those areas. The place looked like the moon (all bomb craters!).
it was difficult to know who the enemy was
