ITALY - $35.8 billion: No. 10 but spending less. Over the past decade, Rome decreased state military spending by 13.3 percent – more than any other country in the top 10. According to Stockholm-based SIPRI's annual report, of the 19 states in the G20, only Argentina, Indonesia, and Italy did not increase their military spending in 2009.
INDIA - $36.3 billion: The only Asian country in the top 15 aside from rival China. India spent the ninth highest amount of any country worldwide. That’s a 67.3 percent increase over the decade, according to SIPRI.
SAUDI ARABIA - $41.2 billion: The biggest military spender in the Middle East has increased defense investments 66.9 percent over the past decade. In 2009, the world’s second-largest oil producer increased its military expenditure by 2.7 percent, making it 33 percent of the total national budget. Such increases have created Saudi Arabia's first budget deficit since 2004, according to SIPRI. Saudi soldiers walk near the Khoba front-line border with Yemen on Jan. 27. Fahad Shadeed/Reuters

JAPAN - $51 billion: The world’s second-largest economy is focusing revenues away from military, decreasing such spending by 1.3 percent over the past decade. That’s less than 1 percent of total GDP, whereas the US spends 4.3 percent of GDP on its military, and Saudi Arabia spends 8.3 percent.
RUSSIA - $53.3 billion: The Russian bear’s military spending saw a 105 percent increase from 2000. Strong oil revenues over the past decade helped Russia beef up its military, though the rate of increase has slowed in the past year because of falling gas prices.

ENGLAND - $58.1 billion: London increased military spending 28.1 percent over the decade. As a percentage of GDP, that’s 2.5 percent, and about in line with the world average of 2.7 percent. At the end of 2009, the UK had 9,500 troops in Afghanistan, followed by Germany (4,280), France (3,750) and Italy (3,150) – all countries among the top 10 military spenders.

CHINA - $100 billion: Beijing regards its military expenditures as a state secret, but SIPRI estimates that China spent $100 billion on its military in 2009. While this is less than one-sixth of what the US spends on its military, it is still a 217 percent increase from a decade earlier.

UNITED STATES - $661 billion: The world's biggest defense budget increased by 75.8 percent from 2000. Overall, President Barack Obama’s defense budgets involve some ‘rebalancing’ of priorities from the George W. Bush era, but no major strategic shift, according to SIPRI. The US’s fiscal year 2011 budget is expected to rise to $739 billion.
