Sure! The price for loaning out Rumsfeld for 30 days should be:
1) The voluntary surrender of all French nuclear weapons to the US.
2) The voluntary resignation of France from the UN Security Council in favor of Japan.
3) The complete dismantlement of any French foreign intelligence agencies (see: false information feeds to allies).
Regarding your point #3. We should definitely disengage from French "intelligence" agencies with all deliberate speed. Any information we share with them is "from our mouth to Bin Laden's ear".
