No, because Iran and America don't engage the world with the same peaceful demeanor. Again, it's objectively true that Pax Americana has brought about a heretofore unheard of level of world peace. The entire world is mostly at peace. War, where it exists, is controlled (and frankly, every war today can be ended at America's behest).

But, realistically, if you were to work for Iran's weapons program, while you wouldn't change any of the outcomes, you also wouldn't necessarily be making things worse. The US still has way more firepower and is actively working to acquire more.
