The point would be to limit Iran's ability to produce nuclear weapons or exercise its influence through the region by every means possible short of war -- and to be prepared to sustain the effort over years, maybe decades. It's an option that has been lurking at the back of the debate about Iran for years. "In their heart of hearts I think the Obama administration knows that this is where this is going," [former Clinton official Kenneth] Pollack says.
I suspect he's right. I also don't expect Obama and his aides to begin talking about a policy shift anytime soon. For the next few months we'll keep hearing about negotiations, sanctions and possibly Israeli military action as ways to stop an Iranian bomb. By far the best chance for a breakthrough, as I see it, lies in a victory by the Iranian opposition over the current regime. If that doesn't happen, it may soon get harder to disguise the hollowness of Western policy.
