Sorry, DJ, will try to stay on topic. The US actions in Mindanao in the early 20th century are extremely pertinent to the early education and mentors of President Duterte and his opinions and policies today. Remember, Duterte, although born in Leyte, moved to Davao at age 27 in 1972 and lived there until being elected President. The actions of the US during the Scarborough crisis in 2012 are of concern to many Filipinos today. They bear a great deal on current government policies. And please don't take this as bashing, but the US's recent intervention in Philippine politics with its use of visa restrictions has caused this problem to come to a head. De-colonization of libraries and US thought and the US lack of history and geography education (indeed in the Philippines and throughout the world also), is not helpful to an understanding of world politics. Wikipedia is a fairly accurate, unbiased, and simple summary of actions in the wars and colonial administration in that time period.
