"Evaluated intelligence indicates that terrorist groups continue to target commercial aviation and are aggressively pursuing innovative methods to undertake their attacks"[1]
It says nothing about them making progress. Also that's a pretty nebulous statement. "Evaluated intelligence indicates"? Why not share the details with the public in the form of a redacted report?
Could you imagine the Surgeon General in the US issuing a statement that some food causes cancer and then not releasing any of the details? Of course not.
Withholding details that allow your citizens to make their own informed decisions regarding their safety and welfare is unacceptable.
Also did anyone ever assume that terrorists had stopped being interested in damaging aircraft? We are reminded of that every time we fly in the US and are berated and abused by TSA personal. So this isn't really a new development is it?
