Seems like a lot of people think that the Iranian government is like other governments. They are jihadist, you can't negotiate or come to terms with jihadist as their motivation is to exterminate you.
The problem of Iran having ballistic missiles, drones and nuclear weapons will never be eliminated until the source is eliminated.
Iran is a great candidate for nation building, they have a population that is one of the most educated in the world. Imagine Iran as a liberal democracy, it would transform the ME.
