What the US wants from the UK for Bush's visit

A complete closure of the London Underground. Shoot-to-kill authority, plus diplomatic immunity in the event of a shooting - a literal license to kill for every one of Bush's 250 Secret Service bodyguards. US jets and helicopters patrolling the skies over London. A moving "sterile zone" policed solely by US agents and troops. Permission to use a minigun on "rioters".

These are not the requests of a visiting friend and ally; they are the demands of an Imperial state towards a client.
