April 16 Vice President Richard Nixon declares that the United States may soon have to “face up to the situation and dispatch forces” because “the Vietnamese lack the ability to conduct a war or govern themselves.” Reaction was swift, impassioned, and came from across the entire political spectrum. [[vii] Senator Ernest Gruening and Herbert Wilton Beaser, Vietnam Folly (Washington, DC: National Press, 1968), pp. 100-105. Thousands of letters and telegrams opposing US intervention deluged the White House. An American Legion division with 78,000 members demanded that “the United States should refrain from dispatching any of its Armed Forces to participate as combatants in the fighting in Indochina or in southeast Asia”[Gruening and Beaser, p. 105]. There were public outcries against “colonialism” and “imperialism.” Senators from both parties rose to denounce even the contemplation of sending US soldiers to Indochina. The Monday after Nixon’s Saturday speech, for example, Senator Ed Johnson of Colorado declared on the Senate floor: “I am against sending American GI’s into the mud and muck of Indochina on a blood-letting spree to perpetuate colonialism and white man’s exploitation in Asia.”[Gillen, 379-383, 402. As Gillen notes, some sources incorrectly attribute this speech to Lyndon Johnson.] This public outcry, perhaps explains why the US then pursued its Southeast Asian policies in secret.
