Most historians continue to hold Marcos responsible for the Plaza Miranda bombing as he is known to have used false flag operations as a pretext for martial law . There were a series of deadly bombings in 1971 , and the CIA privately stated that Marcos was responsible for at least one of them . The agency was also almost certain that none of the bombings were perpetrated by Communists . US intelligence documents declassified in the 1990s contained further evidence implicating Marcos , provided by a CIA mole within the Philippine army
