The world's biggest defence budgets

THE ten biggest defence budgets for 2010 add up to a total of more than $1.1 trillion, according to the latest Military Balance report from the International Institute for Strategic Studies (IISS), a think-tank. The defence budget of America alone, at $693 billion, accounts for more than 60% of the total. But when defence spending is compared to the overall size of each country's economy, Saudi Arabia tops the list. It spends over 10% of GDP on defence, more than double the proportion spent by America. China ranks second in the world's biggest defence budgets (spending some $76 billion) and also boasts the largest armed forces. Only America, India, Russia and North Korea (not shown) have more than 1m military personnel. Defence budgets have grown since 2005, but the balance of military power may be shifting. Western countries, many of which are engaged in Afghanistan, now face budget constrains and cuts, whilst emerging economies, such as Brazil and China, have increased military spending in line with economic growth.
