The Grassy Nollingtons out there could claim that Russia (who controls the large valves in the supply to much of Europe including the UK) could monopolize our gas supply.
heh. that institution of Russia IS going to monopolize the gas supply (to all Russians out there: notice that I wrote "institution" so I _don't_ mean Russians as a nation!!)
It can't control other countries by military power any more, so they look for other ways (Ukraine, Belarus, Latvia and recently Estonia - Russian companies cut (in some cases temporarily) their gas/oil supply for those countries because those countries don't do what Putin says...).
Taiyo.uk don't forget that 15 years ago there was a country called USSR and Putin once said that fall of this country (and, as a result, widely understood freedom for milions of people) was the greatest disaster of XX century.
As for Arabian oil - I don't know the subject so well, but I think it is possible that they try to monopolise the oil industry, but if they do then it has only an economical background (like in case of Microsoft's monopoly), contrary to Putin's political and ideological reasons. So it's not that bad in case of Arabs - they have their oil and they sell it on their conditions. As someone said here before - if you want to be independent on their oil then develop alternate source of energy (same as - if you don't like Microsoft's produtcts then just don't use them).
