The situation in Iran is very complicated because it is a regime that is very vocal against U.S. interests, that has important sources of wealth like oil and natural gas (even if the country itself is far from being wealthy or developed), and it has had access to uranium, which could be used to produce nuclear weapons.
Explanation:
However, forging a deal with Iran, with the support and in conjunction with the European Union, and other international organizations is a better alternative that direct confrontation with the country. The reason is that it is very difficult to topple the Iranian Regime, it enjoys popular support, and the country itself would be very hard to invade due to the mountainous terrain.
Doing nothing should never be an alternative in international relations, let alone when it comes to Iran. The cons far outweigh the pros, and Iran could use the time to become even more aggressive against U.S. interests and allies.
