I can heartily recommend James Sherr's weighty paper: "Russia and the West: a Reassessment", published just a few days ago. It can be downloaded here
There is a hell of a lot in it for readers to think about.
Particularly interesting is the section entitled 'Energy', and its analysis of the Russian-Ukrainian gas business.
p.s. Tonight in a television interview, president Yushchenko warned against making changes to the 'gas market', in particular re-evaluating the price for transit of gas across Ukrainian territory. His waffling comments must fill the hearts of those trying to get rid of parasitic intermediaries and obtain the best possible deal for Ukraine, with dismay.
"I have warned those people who are engaged with this question - the head of the national stock company [Naftohaz] in particular. I know it is fashionable to throw into public discussion the revision of this or other sector of the market, including the gas [sector]," said Yushchenko.
