Global arms spending flat in 2011World military spending failed to rise last year for the first time since 1998 in what could herald a major trend break, but the global nuclear threat remains strong, think tank SIPRI said Monday.
As the global economic crisis cuts into defence spending, conflicts around the world are also becoming smaller, shorter and less deadly, and the number of wars between states are at historically low levels, the Stockholm International Peace Research Institute said.

World military expenditure in 2011 was essentially flat at $1.73 trillion -- an increase of just 0.3 percent from 2010 -- representing 2.5 percent of global gross domestic product or $249 per person, SIPRI said in a report.
"However, it is still too early to say whether this means that world military expenditure has finally peaked," the think tank wrote.
Nuclear arsenals declined last year, the report said, as the United States and Russia further reduced their inventories of strategic nuclear weapons.
At the start of 2012, eight countries -- Britain, China, India, Israel, France, Pakistan, Russia and the United States -- held some 19,000 nuclear warheads, compared to 20,530 at the start of 2011, it said.
However, long-term modernisation programmes under way in nuclear states "suggest that nuclear weapons are still a currency of international status and power," SIPRI researcher Shannon Kile said.

"We have witnessed the practical disappearance of wars between states -- with numbers at a historically low level," armed conflict researcher Neil Melvin told AFP.
Nowadays, "violence emerges within states, escalating from political opposition to civil wars," as in Libya and "it seems we are reaching that point with Syria," Melvin said.
Finally, the think tank said the Arab Spring demonstrated the growing complexity of armed conflict.
