In early April 2009, American journalist Marc Ambinder predicted that the president with time would have to take a more pragmatic stance on the legal status of detainees. Meanwhile, professor of international politics Daniel Drezner suggested the Obama Doctrine was influenced by French philosopher Montesquieu, whose thinking in Drezner's words could be crudely summarised "useless conflicts weaken necessary conflicts." The Obama Doctrine, in Drezner's interpretation, was to abandon foreign policies that had proven fruitless and unpopular, in order to focus on more important and pressing issues. On April 16, E.J. Dionne wrote a column for The Washington Post expressing a highly positive view of what he saw as the Obama Doctrine. The column came in the direct aftermath of the successful rescue of Captain Richard Phillips from Somali pirates. He defined the doctrine as "a form of realism unafraid to deploy American power but mindful that its use must be tempered by practical limits and a dose of self-awareness." Dionne also pointed to the influence Reinhold Niebuhr has on Obama, and quoted Niebuhr's warning that some of "the greatest perils to democracy arise from the fanaticism of moral idealists who are not conscious of the corruption of self-interest" and that a "nation with an inordinate degree of political power is doubly tempted to exceed the bounds of historical possibilities."
