Major speeches by Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.), both potential presidential contenders in 2020, issued a challenge ... to the foreign policy establishment in both parties. Sanders and Warren ... have both issued direct indictments: Sanders at Westminster College and at the School of Advanced International Studies, and Warren at American University and in the pages of the establishment journal Foreign Affairs. Both Sanders and Warren embrace the growing Democratic opposition to wars without end and without purpose. Both Warren and Sanders would end the 17-year war in Afghanistan; both would cut the military budget. And both oppose the trillion-dollar commitment to a new nuclear arms race. Sanders evokes a "global struggle" between the "movement for democracy, equalitarianism, economic, social, racial and environmental justice" and a "growing worldwide movement towards authoritarianism, oligarchy and kleptocracy." Warren echoes that "democracy is running headlong into the ideologies of nationalism, authoritarianism and corruption." Sanders and Warren argue ... that the new authoritarians are rising because of the failure of the global economic order.
