"1. They have made umpteen hundred centrifuges to purify atomic material "
Something even we could do 670yrs ago. Without help.
"2. With the twin tailed f5 they have demonstrated the ability to make high grade forged castings"
Well done, they can forge basic metal. Did you see the Rolls Royce engine programme?
"Keeping the f14 flying, they have demonstrated an ability to make some high grade fourth gen tech conitune to work with no om support. Worth googling some of the articles on these squadrons during the iraq iran war. Very effective fighters and very ingeniuos solutions to the embargo."
F14 was designed in the 60s. That is 50 years ago. Half a century. And they can't build and design them, they can just keep some of them flying.
It is most certainly not 4th gen
The Iranis are just as smart and ingenious as anybody else on the planet, but they are most certainly not technologically advanced.
I never underestimate them, but it is not their tech that we should be concerned about so much as clever asymetric ideas.
