Today I am thinking of the people I’ve met around the world—children, parents, health workers, teachers—who will be harmed by the Trump administration’s decision to try to dismantle USAID and walk back U.S. leadership in global health and poverty reduction.
I’m thinking, too, about the dangerous ripple effects this will cause. In an increasingly interconnected world, we’re all better off when lifesaving medicines are developed and delivered, when disease outbreaks are halted, and when nations lift themselves out of poverty.
Strong leaders throughout history have understood that foreign aid builds a heathier, safer, more prosperous world—and that’s a goal everyone should be able to get behind.
