Dear Yavar, I do appreciate your efforts in creating YouTube channel and uploading Iranian Defense Activities and even more. But, you really don’t need to talk about things about which you have no clue, Okay? Hundreds of Iranian students graduated from high ranked Engineering Schools in 80s spent their military service in Arak complex among them few of my classmates! What do you gain by spreading wrong information on Social media about whose technology was there? Does it really matter now if it is Chinese or Russian?
