Another American risks contracting Ebola while entangled in the Democratic Republic of Congo's endless crises through humanitarian outfits that often serve as extensions of expansive federal programs. This case, amid an outbreak killing hundreds, exposes the folly of U.S. involvement in distant conflicts where limited government resources get diverted from protecting citizens at home. Taxpayers foot the bill for agencies like the CDC to monitor such threats abroad rather than enforcing robust travel controls. The Constitution grants no authority for the federal government to entangle itself in foreign health emergencies at the expense of sovereignty and individual liberty. Original principles demand focus on securing the nation's borders and markets instead of propping up unstable regimes through endless aid. America first means refusing to import the world's problems.
