The current
war between Israel and Hezbollah in southern Lebanon reminds me of nothing so much as the so-called "
Proxy Wars" waged during the Cold War between client states of the US and the USSR. Israel is practically the 51st US state, and Hezbollah is really a proxy for Iran, which, as
this article from Mother Jones explains, is really a proxy for Russia and China.
In other words, the US is in a global struggle with China and Russia for control of oil resources in the Middle East, which is playing itself out in skirmishes along the Lebanese border. In a few years, if the rivalry between the US and China/Russia heats up in the next decade, the current conflict may be seen as the first of the new crop of proxy wars.
Why now? As some have reported, it might be a way for Iran to thumb its nose at Washington, just at the US and Europe were preparing to tighten their demands that Iran stop producing nuclear fuel. In a way, Iran might be showing the West just how much power it has in the region to wreak havoc with the Middle East, which is something that the Bush administration in particular does not want right now, given how badly Iraq is going.
This might have a positive side: as during the Cold War, proxy wars have a way of releasing some tension without having to go to an all-out war, which would be disastrous. They're like little earthquakes releasing tension along a fault. But of course, the threat of a small fanatical group in the Middle East getting their hands on nukes throws a wild card into the equation. That was never an issue during the Cold War.
