So, why doesn't Iran just erase the Wall for now.

I don't know. May be they still have higher priority targets in occupied Palestine, or may be they don't want to look like kikes who don't hesitate to destroy historic artifacts. They think ina different way, not like you or me, so it is hard to tell.

I agree about significance, this will definitely at least significantly delay coming of Antichrist, or could even destroy Apocalypsis prophecy completely. The question is if Persians have similar point of view.
