Hes the young terror suspect who got away, which was not part of the isis plan, a plan that otherwise went off very smoothly. Today another isis video, gloating about the paris but as offensive as the groups propaganda is, they dont lie. Abdelhamid abaaoud, the presumed ringleader of the paris terrorist, popped up regularly in isis videos, and he openly boasted that after fighting in syria, hed been able to reenter europe and buy weapons and even slip through police checks. Francois heisbourg is a security expert and special adviser to the french government. That should set alarm bells ringing. He is taunting them. Yes, he was taunting them. [gunfire] reporter for French Security forces, the paris attacks exposed dangerous flaws. We have been through the gauntlet in the most humiliating manner. Reporter the bottom line is that Frances Police simply cant keep tabs on the 10,000 radicalized young men already flagged, including battlehardened ones who come back from syria through the leaky borders of europes poorer countries. And once theyre in, theyre in, able to live and travel around freely as most of the paris attackers did. France is now pushing for much tougher immigration controls and better information sharing, but most crucial, france needs to double spending on its own Domestic Intelligence services, says heisbourg.

But Salah Abdeslam, europes most wanted man and key suspect in the paris attacks, is still on the run. After evading French Police, he was last seen in belgium. Fearful of police raids carried out in molenbeek, a local man says there is growing resentment amongst the large Muslim Community living there as they feel stigmatized. You have 100,000 people, he said, who will live as if they terrorism. Because of the concern that the Police Crackdown could backfire as the immunity feels abandoned. They are residents of molenbeek, he said, place in which jihadis and suicide bombers are believed to lurk, so residents are rightly concerned for their own safety.

In our cbs news poll out tonight, 36 of americans approve of president obamas handling of terrorism. That is down from 72 right after u. S. Forces killed Osama Bin Laden in 2011. Only 23 of americans believe the president has a clear plan for dealing with isis. His strategy includes air strikes in iraq and syria, and david martin tells us the latest targets include oil. Reporter two air strikes, the most recent over the weekend, have destroyed almost 500 tanker trucks isis uses to smuggle oil and sell it on the black market. By one estimate, the attacks have destroyed roughly half the trucks isis uses to bring in 1 million a day in revenues. Until now the u. S. Has not gone after the tankers for fear of killing the civilian drivers. In these strikes, u. S. Planes first dropped leaflets warning the drivers. And then they conducted runs to scare them away. The u. S. Has also loosened the rules on civilian casualties. Previously a strike would be called off if any civilians were spotted in the area. For these, more than five civilians had to be in the target area before the strike would be called off. The french have now begun launching strikes against isis from an Aircraft Carrier in the eastern mediterranean. The russians have fired a total of 42 cruise missiles against isis targets in syria. Cutting off oil revenues will degrade isis, but the quickest way to defeat it on the battlefield is to seize its capital of raqqa in syria. The red line on this pentagon map shows how close u. S. Backed fighters are to raqqa, just 30 miles to the north and 100 miles to the east. U. S. Officials say the fighters to the north dont have enough the fighters to the east must first push south to seize a key road junction before advancing on raqqa. The fighters will be assisted by 50 American Green beret, but they are not expected to get there until next month. Think of it as a race against time, scott. Can u. S. Backed fighters seize raqqa before isis can launch another terrorist attack against the west . Reporting from the pentagon tonight. David, thank you.
