In a show of trans-Atlantic unity, President Obama and British Prime Minister David Cameron pledged a joint effort on today to fight domestic terrorism following deadly attacks in France. They also strongly urged the US Congress to hold off on implementing new sanctions on Iran in the midst of nuclear talks. Cameron's visit to Washington came one week after 17 people were killed in attacks in France, heightening fears in Europe and the United States about the spread of terrorism. "This is a problem that causes great heartache and tragedy and destruction," Obama said. "But it is one that ultimately we are going to defeat."
Cameron was blistering in his assessment of those responsible for the attacks, calling them part of a "poisonous, fanatical, death cult." "We know what we're up against, and we know how we will win," Cameron said. He spoke as British police chiefs announced that the Paris attack on a kosher supermarket and anti-Semitic rhetoric from extremists had led them to study ways to increase protection for the Jewish community. As Obama and Cameron met at the White House, representatives from their countries were joining negotiating partners for another round of nuclear talks with Iran. Both leaders strenuously urged Congress to avoid ordering new economic sanctions on Iran in the midst of those negotiations, arguing that doing so could upend the delicate diplomacy.
