All of the following are reasons why President Nixon expanded the Vietnam War into Cambodia in 1970 EXCEPT:
Nixon hoped that destroying the supply bases along the Ho Chi Minh Trail would weaken the Vietcong and allow American and South Vietnamese forces to operate more effectively.
After supply bases along the Ho Chi Minh Trail were destroyed, Nixon believed that the North Vietnamese would be more likely to negotiate a peace treaty.
Nixon believed that college students would support his decision.
The North Vietnamese and the Vietcong had been using a supply route called the Ho Chi Minh Trail, which ran through Laos and Cambodia
