Subsonic wind tunnel   Was unveiled Iran Aerospace research

You do mean subsonic right? Below the speed of sound?

England. 1746. The USA didn’t build one until 1920. Is that what you meant? The gains your nation has made are impressive but they don’t make you the master of other nations.
Peyman, you buy many sanctioned items from nations that don’t participate in the sanctions. So what? The sanctions aren’t designed to prevent progress in Iran, they are designed to get your government to talk seriously about issues between us.
Getting closer to war is no victory.

IRAN WAS First or usa?
Please WobblyJoe Study history

You misunderstand the sanctions completely. They aren’t designed to do anything except get Iran to end its hostility and talk. Yes, you built a windtunnel yourself and that’s a good thing but finally having technology from before my parents were born doesn’t make you the Master of the US. It makes you a blowhard.
I am impressed by Irans great progress, but it doesn’t make you master of other nations. Which is obviously what Iran wants.

It’s cool peyman. Really.
But why does a subsonic wind tunnel make you the master of the USA and Isreal? Its only a subsonic windtunnel, most nations have had them for 50 years or more. It’s another lightbulb. (wow, we built a lightbulb!)
