  • To help Nol, Nixon sent 50,000 ARVN and 30,000 US troops to invade Cambodia and ordered secret bombing raids.

  • He kept the bombing raids secret
Successes for the US

Successes for the US

  • 11,000 communists were killed and Nol’s government stayed in power to fight the communists.
  • Huge damage was done to the Ho Chi Minh trail and tonnes of weapons and supplies were captured.
  • However, this didn’t stop the North Vietnamese using parts of the trail that went through Laos to supply South Vietnam.
Reality

Protests

Protests

  • There was public outrage in the USA which led to many protests.
  • Congress cancelled the Gulf of Tonkin Resolution, limited military funding and called for Vietnamisation to be sped up.
