I wouldn't worry as much. You'll never be in quite the mess Syria is in, since Syria is a crossing point for the interests of too many countries. Not only there's easy access for jihadists from all over the world to get there, but also Russia has military bases, which automatically makes the US want to topple over the Syrian government by civil war and the Russians willing to support Assad to protect their interests.
The Philippines are island located, which means it will be harder for terrorists to receive reinforcements. Also no Russian bases are present, so no motive for conflict there either.
It is temporarily not. Duterte a few months ago hinted at the fact that Russians will always be able to use the territory of the Philippines for its Navy. What is this if not an attempt to negotiate with the Russians. Where Russian there is always no stability. Religion have nothing to do with terrorism. Terrorists used by politicians to achieve their goals, and religion is only a way to find people who easily succumb to propaganda.
