Many areas in Vietnam are purposefully flooded to make marshes/swamps. Vietnam asks for weapons from Yugoslavia. More MIG's are purchased. Barricades are built in Saigon and many other important cities. More people are recruited into the army, as everyone wants to protect their families from the baby killing Australians. Mines are laid in the water, as submarines run rampant in the South China Sea.
Also, China, if Australia takes us over, China will have democratic baby killers right next to them. Also, they can help the USSR and give us some troops.
Vietnam asks for military advisors from Cuba and the USSR.
Also, Australia violated the UN vote by buying maple syrup from Canada. We ask for punishment to Australia.
