Sell F-16’s to iran?

I can’t remember why we ever sold F-16 jets to Venezuela, but as relations between that country and ours have become strained lately, we’ve stopped selling them spare parts.  So they’re considering selling them to Iran.

Say, what?  Iran can’t buy Russian SU-35’s?  Because that’s what Venezuela is planning to do.  Maybe Russia won’t sell advanced jets to Iran, which should be a clue to Venezuela.

And a clue to us.  When we sell advanced equipment, why don’t we have the ability to disable same by satellite?  We send out a super-duper-secret signal and zap!  Fried computers.  Good luck flying an F-16 without its computers.  The same should work with any advanced weapon.
