Tehran's thugs cannot last.
But when the crops fail and the cities rot and the children's teeth decay and nothing works except the ever-enthusiastic and illiterate young lads of the morality police, who will the clerics blame? They are not allowed to blame themselves, except for being insufficiently zealous. Obviously it must be because the Jews, the Crusaders, the Freemasons have been at their customary insidious work. Thus, holy war must be waged on happier and more prosperous lands.
If you think I exaggerate even slightly, consult the Web sites of the Iranian theocracy and of its Hamas and Hizbullah surrogates and proxies. These exhorting leaders are not content to inflict their doctrines only on their "own" people. A failed state that cannot allow any grown-up internal debate, or any appeal against the divine edict, will swiftly become an even more failed state and then a rogue one because its limitless paranoia and self-pity must be projected outward.
Thus we have a very direct interest in having the Iranian people permitted to interfere in their own internal affairs, and a very immediate reason to insist that the regime's thugs not make their next appearance on the historical stage with nuclear weapons with which to undergird their claim of unfailing righteousness and conviction that they alone know what it is to be a victim.
