First, the good news: During an early morning raid in Paris Wednesday, French police fired 5,000 rounds of ammunition, survived a woman detonating a suicide vest that partially collapsed the building, killed two people and arrested eight others. While investigating the aftermath, they identified one bullet-ridden body as Abdelhamid Abaaoud, the homicidal dog that planned the attack in Paris.

The Belgian national who the Islamic State considered its “emir of war” was originally thought to be in Greece, but then law enforcement discovered that he had crossed international borders and was in Paris. City prosecutor Francois Molins said the raid thwarted another terrorist attack. “We have reason to believe, given their weaponry, given their structured organization, and their determination, we have reason to believe this commando cell could have moved to act,” he said.

But France’s terrorism problem isn’t over. And it’s not because French President Francois Hollande announced that his country will continue to accept 30,000 Syrian refugees over the next two years despite the known threat of Islamic State fighters posing as Syrian refugees. France said it would increase its scrutiny of the refugees it accept, but whether that increased scrutiny works is yet to be seen. We have to remember the increased regulation only affects law-abiding refugees. The Islamic State, being the band of outlaws that it is, will find other ways of reaching Europe and there is little France or any other European country can do of stopping it because the borders between the countries are completely open. The border between France and Belgium is like the border between New York and the rest of New England.
