The reason I asked, is this article (among others) and a percentage of the population just being completely fed up.
Only slightly more than a third of Americans felt the U.S. should help other countries with their problems. The election of a President who champions “America first” sentiments — and who wants to slash diplomacy and development funding by a colossal 32% — confirmed it as well.
Americans deserve to know the daily return they receive on their investment in diplomacy and development. That investment is small — just 1% of the U.S. federal budget — compared with its impact, but the rationale must be persuasive for each and every dollar. In the last three years alone, American global action has stopped the Ebola epidemic, rallied more than 65 partners to fight ISIS and led 195 countries to forge a historic climate change agreement — before Trump blithely turned his back on our best shot yet at saving our planet.
With a world in disarray and a President seemingly uninterested in it, one would be justified in thinking the best days of American foreign policy are long behind us. But, with so much at stake, it is imperative that we fight against the tides of isolationism. The source of our country’s strength — our greatness — has always been our willingness to lead in a world darkened by danger. While not perfect, our leadership has ushered in an undeniably more prosperous, more secure, more tolerant, more peaceful world. The success is evident all around us. Now, we must do more to demonstrate it.
