The Russian invasion of Georgia has not changed the balance of power in Eurasia. It simply announced that the balance of power had already shifted. The United States has been absorbed in its wars in Iraq and Afghanistan, as well as potential conflict with Iran and a destabilizing situation in Pakistan. It has no strategic ground forces in reserve and is in no position to intervene on the Russian periphery. This, as we have argued, has opened a window of opportunity for the Russians to reassert their influence in the former Soviet sphere. Moscow did not have to concern itself with the potential response of the United States or Europe; hence, the invasion did not shift the balance of power. The balance of power had already shifted, and it was up to the Russians when to make this public. They did that Aug. 8....

The Russians also know something else that is of vital importance: For the United States, the Middle East is far more important than the Caucasus, and Iran is particularly important. The United States wants the Russians to participate in sanctions against Iran. Even more importantly, they do not want the Russians to sell weapons to Iran, particularly the highly effective S-300 air defense system. Georgia is a marginal issue to the United States; Iran is a central issue. The Russians are in a position to pose serious problems for the United States not only in Iran, but also with weapons sales to other countries, like Syria.

Therefore, the United States has a problem — it either must reorient its strategy away from the Middle East and toward the Caucasus, or it has to seriously limit its response to Georgia to avoid a Russian counter in Iran. Even if the United States had an appetite for another war in Georgia at this time, it would have to calculate the Russian response in Iran — and possibly in Afghanistan (even though Moscow’s interests there are currently aligned with those of Washington).

In other words, the Russians have backed the Americans into a corner. The Europeans, who for the most part lack expeditionary militaries and are dependent upon Russian energy exports, have even fewer options. If nothing else happens, the Russians will have demonstrated that they have resumed their role as a regional power. Russia is not a global power by any means, but a significant regional power with lots of nuclear weapons and an economy that isn’t all too shabby at the moment. It has also compelled every state on the Russian periphery to re-evaluate its position relative to Moscow. As for Georgia, the Russians appear ready to demand the resignation of President Mikhail Saakashvili. Militarily, that is their option. That is all they wanted to demonstrate, and they have demonstrated it.

The war in Georgia, therefore, is Russia’s public return to great power status. This is not something that just happened — it has been unfolding ever since Putin took power, and with growing intensity in the past five years. Part of it has to do with the increase of Russian power, but a great deal of it has to do with the fact that the Middle Eastern wars have left the United States off-balance and short on resources. As we have written, this conflict created a window of opportunity. The Russian goal is to use that window to assert a new reality throughout the region while the Americans are tied down elsewhere and dependent on the Russians. The war was far from a surprise; it has been building for months. But the geopolitical foundations of the war have been building since 1992. Russia has been an empire for centuries. The last 15 years or so were not the new reality, but simply an aberration that would be rectified. And now it is being rectified.
