It seems you are the one confused here. Ukraine only sold Iran the missile, it did not help Iran in reverse engineering the missile. You keep mixing up selling the missile with selling+tot/reverse engineering.
Okay, you are the one that is really confused.
Reverse engineer - Definition and More from the Free Merriam-Webster Dictionary
Full Definition of REVERSE ENGINEER
transitive verb
: to disassemble and examine or analyze in detail (as a product or device) to discover the concepts involved in manufacture usually in order to produce something similar
So you are saying the missile that Ukraine sold to you never helped you in designing your own missile? None whatsoever? Nada? Zip? I don't care if Ukraine didn't help with tot. Iran has already shown that they can make clones like ScanEagle and RQ 170 without U.S. helping Iran with tot, correct?
Don't forget the missiles we bought from Ukraine according to reports due to the lack of maintenance were not operational.
so we could not just copy them.
When you say lack of maintenance? Are we talking missing parts? Or degraded you just need to replace them?
Just to be fair, when the ex-USSR split up, everyone, i mean everyone on this planet with some money was buying some thing from the ex republics, including the US who has gotten her hands on the S-300 system to "study it"!
Would that be equivalent to ScanEagle and RQ-170 as studying it? Do you see the American version of the S-300? No, to study it would be how to counter it with its strengths and weaknesses. We got our hands on the MIG 25 by the defector of the Soviet pilot. Does any of the aircraft look like that after we got our hands on it?
