What if, instead of Annexing the Philippines after the Spanish American war, America made the semi-independent but gave them a Platt-Amendment to their constitution. This could be because of anti-imperialists scoring a victory in government, or McKinley not wanting a massive guerrilla war after someone runs the numbers with him. After all, the war had just been won easily, and it seemed a shame to have so many casualties trying to annex the Philippines after liberating Cuba. OTL, the Filipinos killed more Americans than the Spanish.
