The kind of enemy we face these days is not the kind of enemy that the F-35 is designed to fight.But that's the nature of these things- we buy kit that would have helped us in the LAST war we fought.
We'd do better with larger numbers of less sophisticated and expensive aircraft.
It's all terribly obvious, but clearly nobody has the balls to grasp the nettle and pull the plug.
Oh well, the longer they leave it, the messier it's going to be.
Sounds like Canada has wised up though, and I bet they're not the last...
