Sorry, but that is not a very credible criticism against US. You can say the same for the USSR and China. But of course, we know you would not. The intellectual inconsistency is ignored.
But no military academy, including Iran's, will take that argument seriously. Why? Simply put, they know better. A gun that is bought can kill as quickly as the gun that is self made. In fact, the weapons that are imported have passed testing and perhaps even killed, so why would you want to spend your own resources and lengthy time to develop your own?
What you do not like to consider are the quality of your troops, the training, the war doctrines, and the list of intangibles that are equally if not more important than guns, tanks, or aircrafts.
I know I did.
I was. But I guess you were not.
Very few US bases overseas are US designed and built. So we have to make do with what we are given by our hosts. The fact that you do not know that pretty much rendered the rest of your post meaningless.
Considering the posts I read from the Iranians members here, that would be your names.
