Take out a partition wall and you repaint by the weekend. Take out a load-bearing one and everything above it starts looking for somewhere else to put its weight. For four decades, every sanctions architect who drew plans against Iran's economy worked around one load-bearing wall they could not touch: Dubai. Washington could designate, license, and threaten, but the wall stood in someone else's building. On August 19, the owner took it out himself.

Four of this desk's panels worked the same question from different ends: what changes when the wall under Iran's sanctions survival is removed by the sovereign who owns it, while a naval blockade has already emptied the building. The shared answer, HIGH confidence: the severance works on money now and on architecture later, because the water took the trade volumes first.
