The reasons NOT to attack Iran

Writing in the International Herald Tribune, former US National Security Advisor Zbigniew Brzezinski tells the United States why they should not attack Iran.
I hope they're listening:

. . . there are four compelling reasons against a preventive air attack on Iranian nuclear facilities:
1. In the absence of an imminent threat (with the Iranians at least several years away from having a nuclear arsenal), the attack would be a unilateral act of war. If undertaken without formal Congressional declaration, it would be unconstitutional and merit the impeachment of the president. Similarly, if undertaken without the sanction of the UN Security Council . . . it would stamp the perpetrator(s) as an international outlaw(s).
2. Likely Iranian reactions would significantly compound ongoing U.S. difficulties in Iraq and in Afghanistan [and would likely] cause the United States to become bogged down in regional violence for a decade or more to come. Iran is a country of some 70 million people and a conflict with it would make the misadventure in Iraq look trivial.
3. Oil prices would climb steeply, especially if the Iranians cut their production and seek to disrupt the flow of oil from the nearby Saudi oil fields. The world economy would be severely impacted, with America blamed for it. . . .
4. America would become an even more likely target of terrorism, with much of the world concluding that America's support for Israel is itself a major cause of the rise in terrorism. . . With America increasingly the object of widespread hostility, the era of American preponderance could come to a premature end. . .
The choice is either to be stampeded into a reckless adventure profoundly damaging to long-term U.S. national interests or to become serious about giving negotiations with Iran a genuine chance to be productive . . . American policy should not be swayed by a contrived atmosphere of urgency ominously reminiscent of what preceded the intervention in Iraq.

Emphasis mine. These reasons apply equally well to Canada -- I just hope Harper doesn't think that hiding a few caskets will persuade Canadians to string along with Bush on this one -- actually, NOTHING could convince Canadians to join Bush in attacking Iran.
