Mutt: France is the only country I'm aware of that has grounded aircraft and forced the airline to fly in another Captain before releasing the flight. That is why I used the title "Solving France". The FAA and/or other countries may have cited some crews but I don't think any flights have been delayed as they were in France.
Elliot: I have flown with good and bad F/Os in just about every corner of the planet. I think the point is that the FAA Certified Training and Documentation exceeds ICAO requirements. The fact that another piece of paper is required just gives the bureaucrats (ours and theirs) another victory.
