I usually find your posts insightful, but I don't think the Bush/Blair comparisons work, it just takes my mind to 'Bush and Blair were arseholes for that, and their domestic politics, and so's Putin for this and his domestic politics
' and I don't think that's what you're getting at?
I suppose Bush/Blair were less delusional because the defeat of Iraq was quicker and with less cost to USUK than appears to be the case for Putin/Russia in Ukraine, although the insurgency and rise of isis counts against that.
The Iraqi regime of the time was demonstrably worse than modern Ukraine's too, although I didn't, and still don't, think that justified that invasion
