Italy, Spain, Denmark, The Netherlands, Bulgaria, Czech Republic, Estonia, Latvia, Lithuania, Romania, Slovakia, Ukraine, Norway, Portugal. Which have I missed?

Even Germany is a dumb one, really. The only reason why they didn't participate is because they legally weren't allowed to. What they did do, however, is deploy huge numbers to various US bases around the world so that the US can have a larger deployment.

The only absurdity here is the idea that the European retconning is believable.

Yes it is I who am doing the retconning not the person claiming that tiny contingents of mostly non combat troops sent to Iraq after Bush declared "mission accomplished" in an effort to help clean up Americas mess and with a UN mandate constitutes involvement in the war by all European countries.
