The MOD have created a NoFly zone in Libya.
But it only applies to UK forces.
By chopping all the bits that are needed to support a NoFly zone in Libya and making all the rest of the Boys & Girls too busy to help out, the MOD have ensured there will be no (British Military) flying going on.
So that's a positive spin on it.
Zero casualties. Zero cost. Zero room to move if something else comes along.
