After the student massacre at Thammasat University on 6 October 1976 , Thirayuth , as well as many other students and intellectuals fled from the cities to take refuge with the Communist Party of Thailand ( CPT ) in its jungle strongholds . Thirayuth increasingly became critical of the king , noting in a broadcast on 1 April 1977 that the monarchy was " obsolete and deteriorating " , and that " I think that if our people were to destroy it , there would be no adverse effects " . After the CPT dissolved itself in the early-1980s , Thirayuth returned to the mainstream of Thai intellectual life , renouncing socialism and rejecting his anti-monarchical statements
