Kurt i think you discounted the capabilities of the Euro birds and their AFs too much
as with the APA analysis itself, the Flankers are very capable platform, but we need to look at the individual platform these countries bought, the state they are in, pilot training, maintenance level, and their overall effectiveness
and IMO from what i see, these Flankers are far from the overhyped bird-of-prey APA has been iterating over and over (from Australian perspective)
Australia and Singapore can easily handle them, not to mention the RAF, AdA, or the Luftwaffe
why does the JSF seems to 'fail' so hard?
because it's an excellent strategy from a business point of view, make one product for all your different customers that do everything and anything and backflips, so they drop their legacy platforms and stick to the one and only JSF
which is a disaster in military point of view
