I don't know much about what's going on there, but I've been there, and I could certainly see some situations where executive action is required. If the drugs are that bad...well, maybe it's necessary.
Drugs weren't an in-your-face, violent threat in the Philippines (unlike Mexico).
Yes, there were drugs and drug users and organized crime controlling it. But, to my knowledge, it was lower-key (kinda like Miami in the 1980s). There was violence between drug gangs, but it didn't seem to spill out into the civilian population or into the tourist industry.
The biggest issue in the Philippines is the Islamic insurgency in the south of the country. Abu Sayyif has been a thorn in the country ever since the Moro insurgency died down.
