It is possible that the killing of Osama bin Laden marks the zenith of the American empire. Since the end of WW2, the USA has been the world’s policeman. The end of the Cold War brought a peace dividend of lower military expenditure, but the War on Terror partially reversed this. While the US was financially strong, this was bearable. Now that the US is faced with a dire fiscal and private debt position, it is increasingly difficult to sustain its overseas military position.
US military spending in 2009/10 was $685bn, about 4.7% of GDP, significantly higher than other developed countries. Military spending is about 20% of the total federal budget. The US accounts for about 40% of the total world military spending. With acute budgetary pressure, the need to cut military expenditure to reduce the deficit will be intense.
Many prominent US commentators are questioning what benefit the US gains from its enormous military effort. Here’s one example from Foreign Policy from Douglas Macgregor, a former Colonel in the US army. People and countries can only stand pain and vilification for so long. The US appears to be wearying of being the world’s most hated country.
The death of bin Laden is a pivotal moment as the US can claim that it has eliminated the two most prominent antagonists of the past twenty years: Saddam Hussein and Osama bin Laden. It can claim that it has achieved closure even it cannot claim total victory. The war against Islamic militancy will drag on for the foreseeable future and Iraq is likely to remain unstable. Nonetheless, the US can say that those that challenged it have been eliminated and serve as a lesson to those that might try in the future.
The psyche of the US is still heavily influenced by cowboy movies. A murder is perpetrated; the sheriff and posse is sent out to exact justice. The criminal is caught and hanged. The sheriff and posse return home to resume their lives. Clearly, the real world is more nuanced than that, but there will be a strong feeling in the US that their objective has been achieved and justice has seen to be done.
The process of disengagement in Iraq has already begun. Unless the Iraqi government asks the US otherwise, the US military will leave by the end of this year. With the death of bin Laden, it becomes more likely that the US will seek an honourable withdrawal from Afghanistan.
While the US is likely to retain a strong presence in Asia, not least because China is flexing its military muscles, elsewhere around the globe a measure of retrenchment and disengagement is likely. The Middle East is tricky as on the one hand withdrawal from Iraq will mean a smaller commitment, the US will want to maintain a deterrent to Iran’s regional ambitions as well as safeguard the flow of oil. The big game changer would be any technological advance freeing the US from its dependence on imported oil, but that is likely to be at least a decade away.
In some ways, there are parallels with the Britain and the dissolution of its empire. After the Second World War, it became clear that the UK was no longer in a position to maintain an empire. The cost of two world wars had been too great. With the bogey of German aggression, epitomised by Adolf Hitler removed, Britain decided to retrench and recuperate. Arguably, this process is still not complete.
The US has probably reached the same point, where it has become excessively stretched, both financially and motivationally. As with Britain, this process will stretch over a decade or two. Unlike Britain, it doesn’t have to grant independence to countries, so the process might be more rapid. However, those that vilify the US, might regret what they wished for. A world where the US is less inclined to be the policeman is likely to be more volatile and unstable.
