The notion that Spain and/or Greece might spend $bns on a 5th-gen stealth fighter, with no prospect of significant workshare, is utterly implausible given the state of both nations' finances now and for the foreseeable future. Even the vague 'threat' from the Turks against the Greeks gets nowhere near pushing it high enough up their national spending priority list. Plus, if I was German, I would be mightily annoyed that countries surviving on piles of my hard-earned cash were spending it on highly-advanced, predominantly US-built military equipment! It simply won't happen.
