As the Spanish-American War ended in 1898, President William McKinley stunned his Philippine allies by deciding to annex the archipelago — and precipitating a bloody conflict.

He’s harkening back to U.S. massacres, suggesting that one of Washington’s staunchest allies isn’t afraid to look elsewhere — even to China — for friends.
