Duterte, a lazy-minded and not so psychologically stable Marcos idolater, has been looking to precook the right emergency, and he seems to have decided on the most recycled one: everyone who's after him is a communist son of – as he is wont to say of anyone he dislikes – a not so very nice mother. He's hoping it would make for a salable pretext for declaring martial law or a revolutionary government. If he has been unable to act on his plot yet, the only plausible reason I can think of is he has not sold it fully to the indispensable armed forces.
