If you can not do the two maneuvers stated, in a F-16 or F-22 you will
never beat the Griphen. The russian mig-30 that literally stops in mid
flight and recovers, is another example. A forward canard allows this.

It is a critical failure of US technology.

It would be delusional to flatter yourself into thinking you know more
about canards than do the U.S. aircraft designers who decided against
using them.
