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?
Instead, they will fight this war by absorbing blow after blow, hiding their capabilities and striking back when it is advantageous.
All Iran needs to do to win is:
1) Outlast the US air campaign - note this only requires protecting enough of their defensive capabilities to remain difficult. It does not require shooting down every US aircraft that enters their borders. It does not require shooting down most aircraft that enter their borders.
2) Prevent free shipping in the Strait of Hormuz.
That's it. They just need to apply economic pain as domestic and international opposition to the unprovoked attack grows.
