For almost 40 years, American national security officials have looked down the barrel of the gun of war with Iran. I sat in rooms in the White House and Pentagon several times as small groups of senior officials considered what such a war would look like, how it would end, and whether we would be better off for having fought it.
The answer was always the same: It would be highly destructive in several nations, it would end in a stalemate with the Iranian regime in place, and nothing positive would have been accomplished.
