The Typhoon and Rafale are all inferior to the F 35 in capabilities.  The Gripen is considered inferior to Typhoon and Rafale and is only been ordered by those countries who cannot afford either the F 35 or the Typhoon or Rafale.

If you really think that "..all of the US fighter aircraft are going to get slaughtered by the three Eurocanard..."  then you should ask why Italy is now assembling F 35's and they operate Typhoons. The UK is buying the F 35 and they also operate Typhoons.

 They and all the other countries that have ordered the F 35 know its real capabilities.

Get used to the fact that the F 35 will dominate sales for decades
