Nixon took over the Vietnam War from Lyndon Johnson and continued it with the strategy of slowly withdrawing U.S. troops, so that the South Vietnamese troops could take over the fighting by themselves. Nixon secretly bombed many enemy targets in Cambodia and North Vietnam while bringing home the American troops, to make it easier for South Vietnam to win. When his spreading the bombing to Cambodia and Laos became known in 1970, it caused larger protests than ever in America, including at Kent State and even in Washington, DC, where more than 12,000 were arrested in May 1971 at the peak of the protests. Partly because of the amount of opposition, Nixon sped up troop withdrawal and ended the draft.
