No matter how you look at that but it becomes more and more obvious USA advisedly contributes to tension in the Caucasus. Simply Washington tries to damage relations between the countries of this region and Iran. It's the main goal of USA at this stage of covert preparations for war against Iran. And US attempt of establishing economic blockade against Iran (with the help of American protйgйs in this region, of course) is only preparatory stage for American future intrusion into Iran's territory. In this case Azerbaijan and Georgia are US main levers of political pressure on Iran now. That is why during his visit to Georgia Bush has pressed to break off contacts between Tbilisi and Teheran. The matter is that Georgia and Iran tried to establish good-neighborly relations in the sphere of supplies of Iranian oil for Georgia. Furthermore, Iran was ready to go a long way down the line in the field of oil prices for Georgia. But immediately USA has objected most strongly to it. And up to now Americans seek to provoke friction between Iran and Azerbaijan in matters of oil supplies for Georgia. At any moment this economic conflict, made with the help USA, may develop into political one.
