WASHINGTON (AP) — Is Rand Paul the next generation-defining senator on American foreign policy?

In just three years, the Kentucky Republican has shaken up Congress and the Obama administration with his brand of isolationism and libertarian populism. He filibustered President Barack Obama's CIA director over drones and led the fight against U.S. military action in Syria.

Even in defeat, Paul has been vindicated. The administration's decision this month to suspend much of its $1.5 billion annual assistance package to Egypt is a course Paul unsuccessfully championed 10 weeks earlier.

Paul objects to much of what represents consensus U.S. policy. He has suggested cutting foreign aid in half and excluding countries, primarily in the Muslim world, that don't share American values.
