The first corporate job I had was with a company that had just made an acquisition of another company with multiple locations. One of the projects I worked on was to figure out by how much the acquirer had been ripped off for missing inventory. The morons who did the deal did the inventory count for valuation purposes by visiting one facility at a time. The seller moved the inventory from location to location - the buyer paid for it 12 times.
Obama is going to be similarly played by Iran with this 24 days notice - only there will be nothing to count after the 24 day notice.
