Why didn't Iran use its capability to take down enemy jets for an entire month?
Downvoters, care to explain? Seriously, it's been sitting on this for entire month and now, all of a sudden, rolled out antiaircraft defense? What's going on?
You sound like they roll an antiaircraft cannon out of the hangar and immediately successfully down a plane. That's not how that works. The AA was probably there from the beginning, just not successful.
