There is a race currently underway between different flanks of the administration to determine the future course of US-Iran policy.
On one flank are the diplomats, and on the other is Vice President Cheney's team and acolytes -- who populate quite a wide swath throughout the American national security bureaucracy...
This White House official has stated to several Washington insiders that Cheney is planning to deploy an "end run strategy" around the President if he and his team lose the policy argument.
The thinking on Cheney's team is to collude with Israel, nudging Israel at some key moment in the ongoing standoff between Iran's nuclear activities and international frustration over this to mount a small-scale conventional strike against Natanz using cruise missiles (i.e., not ballistic missiles).
We now have a vice-president who is not only working against our country's interests, but is actively undermining the president. What are the rules for impeachment of a vice-president again?
I should add, Steve Clemons has more credibility on something like this than almost any other blogger. He is very well-connected in Washington.
