The Philippines Nexus

You remember Muslim terrorists in the Philippines took an American couple captive and ultimately beheaded the man before commandos rescued his partner. You recall Timothy McVeigh's one convicted accomplice was married to a woman in the Philippines. Hearken back to the airplane plot that was thankfully thwarted to use suicide bombers to blow up multiple planes more or less simultaneously that was hatched by jihadists in the Philippines, then consider whether the recent visit by the Australia terrorists to the Philippines might have factored in to the Bondi massacre.
