Shaheds are not at all a problem. Yours truly is one of perhaps hundreds of entities who work on them and in Ukraine, it is a solved problem - virtually none of them ever gets through (question now is how to fight them cheaper and while letting them slip through less Ukrainian territory before being shot down - but in Gulf states it won't a problem, distances are much longer there).

And after pipelines are built, straight will no longer be needed, and Iran will have to negotiate, or end up like Afghanistan (without electricity -> without functioning cities) - no one could call it a victory.
