From a new report (pdf) on global trends in military spending:
The increase in 2010 is almost entirely down to the United States, which accounted for $19.6 billion of the $20.6 billion real-terms increase. Excluding the USA, the total in the ‘rest of the world’ barely changed in 2010, increasing by a statistically insignificant 0.1 per cent.
Greg Scoblete summarizes the rest of the world:
Regionally, defense spending in Europe has fallen 2.8 percent while spending in South America has risen by 5.8 percent and in Africa by 5.2 percent. Brazil drove a lot of the South American growth. Asia rose only a modest 1.4 percent, which the Institute said was slower than previous years. Overall, global military expenditures ticked up slightly at 1.3 percent, the slowest growth rate since 2001.
