I know it will never happen. There is no way Zapatero has the cashews, but he should pull a Reagan and fire all the air traffic controllers. They should be thankful they have a job.
For anyone who is not, shall we say .... OK, as old as me, in 1981 the air traffic controllers in the US tried to pull this same stunt. Reagan gave them 48 hours to return to work and when they didn't he fired 11,000 striking controllers. They hired new people, they used the military to fill in, etc. and it all worked out.... except for the guys who got fired.
