It's the worst assault on Paris since World War II. As France mourns the 132 people killed in Friday's terrorist attacks and prays for the hundreds who were injured, a chilling Islamic State video warns of deadly consequences in the U.S. or any country that joins the French in their airstrikes against ISIL positions in Syria and Iraq. The threat of terrorism is very much alive, even though all of the Paris terrorists, except one, are believed to be dead. A manhunt is underway for Salah Abdeslam, and it expanded Monday into Belgium, which is also home to Abdelhamid Abaaoud, a 27-year-old Belgian named in media reports as the mastermind of the attacks and "one of the most active" ISIL executioners in Syria. Back here stateside, the CIA says it is working "feverishly" to ensure an attack doesn't happen, and President Obama said he's committed to destroying what he called 'the face of evil" — but without U.S. combat troops. And if all of this weren't complicated enough, at least 21 governors announced they were taking action to keep Syrian refugees out of their states for fear ISIL terrorists would make it in, too — even though they might not have the power to do so. And then Republicans in the House and Senate started working to block funding for Obama's plan to bring 10,000 Syrian refugees into the U.S. So much for the reminder from Green Bay Packers QB Aaron Rodgers: "We're a connected world." The Islamic State group released a video showing one of its fighters in Iraq vowing to attack Washington the way Paris was attacked last week. Meantime France's president says he wants to unite forces with the US and Russia against IS.
