there was a US F-16 deal on the cards in the 1990's(?) as well. the French strung them along with an F1 deal after the Spanish one went tits up - of course, it was the French who made the Spanish deal go tits up as they finally told the Spanish that they would not allow the French built aircraft to be sold to Argentina.
after Argentina had spent a fortune on training pilots to fly the F1's...
the French deal didn't last very long, iirc the Argentines had got wind that it was the French who'd screwed them over on the Spanish deal, and the French couldn't keep a straight face.
we shall see if this goes any further, but while its all worth a good laugh at Argentina 'upgrading' to a aircraft everyone else has scrapped, a dozen Kfir with an AESA radar and a handful of BVRAAM's would run our four Typhoons - unless they can be in 6 different places at once - ragged.
