 In February 1965, the VC attacked the American airfield at Pleiku, killing 8 Americans and destroying 10 aircraft.After hearing of the attack, Johnson assembled his national security team together with the Speaker of the House of Representative, John McComack and the Senate Majority Leader, Mike Mansfield, to announce "I've had enough of this".Only Mansfield and the Vice President, Hubert Humphrey, objected to Johnson's plans to bomb North Vietnam.
