Iran shouldn't have nukes, but starting a war—burning billions of dollars a day, killing kids and innocent civilians, and leveling bridges and universities—is objectively the worst possible way to prevent it.

The JCPOA under Obama actually did a solid job of constraining their nuclear development. That was the pragmatic approach, but Trump just unilaterally scrapped the deal. He doesn't have an actual strategy, maybe just "concepts of a plan".
