Time passed and Tuyến began to show displeasure at the increasing interference of Nhu's wife, Madame Nhu into politics; displeasure turned to offense and Nhu began to ignore Tuyến. In early 1963, Tuyến was ordered by Diệm to go home and rest because the latter thought the former had been too lenient with disillusioned military officers and politicians who were veering towards opposition. Tuyến was never recalled to work. Instead, Tuyến responded by dispatching his staff back to their former position they had held before they joined his department, leaving the intelligence bureau in a state of collapse. In May, when the Buddhist crisis erupted after Diệm's forces had banned Buddhists from flying the Buddhist flag to commemorate Vesak, and fatally fired on them, Diệm recalled Tuyến, hoping he could resolve the crisis.
