MIAMI — Sen. Marco Rubio is pushing to make what he calls “decisive” diplomacy and foreign aid the backbone of American foreign policy, separating himself from a growing isolationist wing of the Republican Party.

The Florida senator and potential Republican presidential hopeful will argue in remarks Wednesday at the conservative American Enterprise Institute in Washington that diplomacy and foreign aid should “vastly outnumber” the country’s uses of military force, according to excerpts provided to The Associated Press.
