Republicans and Democrats are trying to contain Trump's Greenland aggression. Will it be enough?

Republican lawmakers are scrambling to contain President Donald Trump’s threats of taking possession of Greenland. Some are showing the most strident opposition to almost anything Trump has done since taking office. But it’s not clear that will be enough as the president continues to insist that he will take control of the Arctic island. It’s raised fears of an end to NATO. It also raises questions on Capitol Hill and around the world about what Trump’s aggressive foreign policy will mean for world order. A bipartisan group of lawmakers traveled to Denmark to try to tamp down the prospect of a conflict between the U.S. and European allies.
