Marcos Administration trained its' Armed Forces to reclaim Sabah in 1968, but it is unsuccessful .. Why is it that the current Administration can't do it again?

The Philippine government raised the Sabah claim during the administration of President Ferdinand Marcos, which urged that the claim be decided by the world court or the United Nations. Malaysia, however, knowing that the Philippines had a valid claim, refused to take the case to an international body. The Marcos administration even thought of sending a guerrilla force to Sabah and went to the extent of training such a force in Corregidor, until a recruit ran to then Sen. Ninoy Aquino to expose the Jabidah massacre. The exposé killed the plan to infiltrate Sabah.
