This graph shows military expenditure as a percentage of GDP. Saudi Arabia is one of the world’s most densely armed nations, largely due to its cutting-edge, high-technology arsenal of weapons, which is mainly supplied by Britain, France and the US. Military expenditure spiked at 14.3 per cent of GDP in 1998. It has since fallen slightly, standing at 11 per cent at the end of 2008. It still ranks among the top ten in the world for government spending on its military.
