Washington (CNN) George W. Bush tried it. Barack Obama and Hillary Clinton tried it. Now Donald Trump is vowing to reset relations with Russia. But could the unintended costs outweigh the benefits? The President-elect's Russian gambit seems like a solid foreign policy goal, given that the estrangement between the rivals -- owners of the world's biggest nuclear arsenals -- is deeper than at any time since the Cold War. An improvement in relations could yield gains for the United States in reviving non-proliferation projects and closer anti-terrorism cooperation. But there are big questions about whether Trump will be any more successful than his predecessors, whose initial inroads eventually foundered largely due to the behavior of President Vladimir Putin, and whether he will end up emboldening a leader that many -- including key Republicans in Congress -- see as a top US adversary.Closer US-Russia ties could revive non-proliferation projects and closer anti-terrorism cooperationBut closer ties could also mean restoring Russian influence at the direct expense of the US 
 Question:Trump has made no secret of his admiration for the Russian strongman, once saying he was a better leader than Obama, and on the campaign trail showed little concern about resurgent _ influence.

Ex Output:
Russia
