A coalition of 51 anti-war groups called on former Vice President Joe Biden to adopt a principled foreign policy that prioritizes diplomacy, human rights and the rebuilding of international relationships and institutions.

The demands, laid out in a Monday letter to the campaign, ask Biden to part not only with many of the policies of President Donald Trump , but also break with some aspects of former President Barack Obamas approach to global affairs and that of many other Democrats .

It is time to end our endless wars and adopt a new approach to international relations, one in which the U.S. abides by international law, encourages others to do the same, and utilizes our military solely for the defense of the people of our country, the groups state.

Given the non-partisan status and varied ideological leanings of many of the letters signatories, the coalition also sent the missive to Trump.

The letter, which the civil libertarian group Demand Progress spearheaded, is nonetheless primarily directed at Biden. It represents the most robust effort to date by the Democratic Partys progressive base to influence the presumptive Democratic presidential nominees foreign policy.
