Let's be real: Iran is not a place that can be conquered without purposeful preparation, internal collaborators and a very well funded long duration campaign. Afghanistan is by far the most difficult place to conquer. Followed by Nepal and Switzerland. Iran and Yemen are 4 & 5 just based on terrain and insurgents. China and India would be easier, and that says a lot about how difficult it is to defeat Iran.
Honestly, what the Hell did Israel and USA think was going to happen? I'm shocked that these two powers thought it would be easy.
