What is the thesis statement for Nixon's "the great silent majority" speech?

During his successful Presidential campaign in 1968, Richard Nixon promised Americans that he had a "secret plan" to end the war in Vietnam. However, early in his Presidency Nixon decided that a quick withdrawal would make the United States appear weak to the rest of the world. In his speech, Nixon claimed that letting the radical minority of protesters, who insisted that the US immediately withdraw all troops from Vietnam, influence his policy would bring defeat and be disastrous for world peace. Appealing to the "silent majority", Nixon asked for united support to end the war and find a peaceful solution. The speech codified the Nixon Doctrine, according to which "the defense of freedom is everybody's business-not just America's business." After the speech, Nixon's approval ratings, which had been hovering around 50%, shot up to 81% in the nation and 86% in the South.
