 The McNamara Taylor mission 's report noted that one of the reasons for sending Tung 's men into the field was because they " are a continuing support for Diệm " . The Americans were aware that removing the special forces from Saigon would increase the chances that a coup would succeed , thereby encouraging the army to overthrow the president . Diệm and Nhu were undeterred by the suspension of aid , keeping Tung and his men in the capital . In private talks with US officials , Diệm insisted that the army was responsible for the pagoda attacks and that Tung 's men were already under the control of the JGS .
