The Bush administration had become radically isolationist, a total U-Turn from Clinton's foreign policy, right up until 9/11, they hadnt paid monies to the UN or anything, they where not trying to influence world affairs in any obvious way at all.
If the US was acting in any way which mirrored or countered Russian influence I'm alright with that, the Russians have behaved very aggressively since they finally got their act together under Putin and its largely unreported.
They've been sabre rattling around the arctic in their ancient subs, conducting fly overs and cloud seeding over the UK (if you can make it rain with silver iodine you can make it rain radioactive or acid rain if you change the chemical mix), they invaded Georgia for being too friendly with the EU, they've positively stimulated islamic threats within their territory, transforming nationalist or seperatist struggles into sectarian ones and been involved in all kinds of spy games, intrigue and assasinations.
The poisoning of Lipvinenko (spelling) was right out of the KGB play book and the use of radioactive water to do it was a message to the UK government about the rain which could fall if they wanted it to you want to hazard a guess if the waiters or restaurant staff or even people eating out will develop cancers in the future?
I hear people saying that this is all Russian government theatre for domestic consumption, that's what the clever diplomats say but you know.
No matter how much of an objection you have to real politik and state violence I tell you this that you would no a difference if anyone but the US was world hegemon, the EU does not want to be so much as a rival to the US, when it behaves in that way it only runs the risk of inviting trouble by making the US appear weaker than it is.
