Intelligence across several countries from various sources indicates attacks are likely on 9/11 in Western Europe and eastward from there. None in the US are being publicly acknowledged. I think if something does go down on 9/11, it will be lone wolf or indpendent cell activity.
The 11 planes missing from Tripoli are not likely to show up in US airspace due to fuel capacities on the models missing.
The incident that tickles me is ISIS capturing Russian planes in Syria and making threats to Putin. Sure, let’s piss off not one but two major world powers. Let’s give them a cause to unify their efforts. How classic will it be when the Western World teams up with Russia once again against a genocidal group of fanatics? How did that work out for Hitler?
