Financial Times reports on 4 July 2005 that the MoD* is making plans for a significant withdrawal of UK troops over the next 18 months. Don't recall seeing the U.S. papers reporting that our staunch ally is making plans to get the hell out of Iraq.
London gets bombed Thursday, 7 July 2005.
A Reuters article gives us a better idea of what Britain's troop levels are: they want to go from 8,500 to 3,000. By mid-2006. That's 12 months, not the 18 Financial Times reported. The leaked MoD documents also spill the beans on DOD's troop level plans - go from the 140,000 now to 66,000 by early 2006.
To borrow from Matthew Cooper of Time - this sounds like a double super secret.
At the time of this writing, a Google search for articles on UK troop withdrawals/MoD leaked documents, returns hits only on foreign news organizations.
It will be interesting to see who Bush/Blair eventually finger for the London bombings, now that they'll have all these troops freed up and nowhere to go.
