I agree, the F-14 is indeed a very beautiful plane. A very iconic one for me during my childhood. The F-22 and F-14 are my favorite birds.
And no doubt, Iranian Tomcat pilots are good. In fact, the Tomcat pilot with the highest killing blows was an Iranian.
Hmm...designing and manufacturing stealth materials is not that hard to be honest. I'm pretty sure even India and China can do it. Though, unlikely to be as advanced as the ones used on the US's F-35.
However, developing a radar, state-of-the-art avionics and a particular shape that'd make the aircraft 'stealthy' is a whole different matter. One need pretty advanced computers do develop such technology.
Manufacturing them is also a matter as well. One cannot produce such advanced weapons like candies in Willy Wonka's chocolate factory.
Oh, and I forgot the engine part, which is by far the hardest part of any aircraft design.
Anyhow, if it weren't for those sanctions, Iran would have become a full-fledged industrialized nation by now.
Emotions can be good for a start. But in the end, or late phases, they do not lead to anything good. And the costs great (not in terms of money).
The F-14 Tomcat has a geometric wing design. Though, it may look cool and all, the design is outdated by today's standards.
That design would allow limited opportunities to reduce its RCS signature compared to that of the F-15 Eagle.
