Sorry about offtopic. I did ok on TANAH,got my 70. Back on topic.
I dont think that many NATO countries will buy JSF, because:
A)Too damn expensive(although supposed to be cheap to maintain).
B)There arent any third world countries that are both hostile and have planes that can match F-16,F-18, Tornadoes etc that NATO counties have now, not even talking about JSF(probadly only thing that can match JSF is new Sukhoi planes).
Non NATO countries or thoose who are not allies of US prefer Russian equipment, coz its cheaper and does its job.
