A call for patience (and vigilence) on Iran

Today's WaPo contained a thoughtful and well-balanced editorial on the US' evolving policy towards the government of Iran.   Their bottom line (which I happen to agree with) is that it would be a mistake to adopt a more aggressive posture towards "regime change" in Iran at the present time.   However, they go on to support the view that a more forceful US policy may be needed if Iran were to go too far:

If Iran escalates in Iraq, refuses more intrusive international inspections of its nuclear facilities or appears to actively harbor al Qaeda, the tougher measures the administration is debating may be necessary. But for now, they are not.
