Looking at it from a different persective....
How come the anks can feed in VFR Cessna 172's in LAX or JFK, how can 152's fly IFR in the airways above LAX (many do), how can 90 Kt warriors be allowed to fly IFR?
Easy because there really isn't a problem. We love to imagine a problem in Europe and look at "worst case", but in reality there isn't a problem....
....we just winge a lot I suppose...
