After declining in the post-Cold War era of the early 1990s, global military spending is on the rise again - threatening to break the US$1 trillion barrier this year, according to a group of United Nations-appointed military experts. The 16-member group estimates that military spending will rise to nearly $950 billion by the end of 2004, up from $900 billion in 2003. By contrast, rich nations spend $50 billion to $60 billion on development aid each year.
