He's a foreign minister. His job is diplomacy, and to iterate the Islamic Republic's position on the matter, and to engage other nations diplomatically on the topic.
He's not responsible for anything else. Putting an Armed option on the table is the responsibility of the Armed Forces and the Government. If they do, he will simply reiterate this position.
So far, what he has been doing is exceptional. Try yourself to fly one nation to another, to endless meetings, preparing endless reports and speeches in advance, and arranging meetings all the while engaging organizations on the issue, all in one week. It's a daunting, tiring, fatiguing task. He has done it exceptionally and with heart as a foreign minister.
Whether or not diplomacy produces results on this issue is a different topic. It's the Government's and the Armed force's responsibility to understand stand this and come up with a solution, not the Foreign Minister's.
So, you have a point and your criticism might be valid, but it's directed at the wrong person or entity.
