The Global War on Terror (GWOT), now into its sixth year, has become one of the most expensive wars in American history. GWOT covers three military operations: Operation Enduring Freedom (OEF), which broadly covers Afghanistan but ranges from the Philippines to Djibouti; Operation Noble Eagle (ONE), which is meant to provide better security for US military bases and enhanced homeland security; and Operation Iraqi Freedom (OIF) which began with the build-up of troops for the 2003 invasion of Iraq. The cost of these operations has phenomenally increased over the years.

On February 5, 2007, President Bush presented his administration's budget for fiscal year 2008 (October 1, 2007 to September 30, 2008). Out of a total budgetary allocation of US $2.9 trillion for all sectors, $623 billion (21 per cent) was earmarked for defence purposes, including those for war efforts in various parts of the world. With the new budget, America's military budget has doubled since Bush took office in 2000 and is now higher in real terms than any other year in the last half-century.

On 29 December 2006, China released its latest white paper on national defence. Though this document is widely perceived as opaque in budgetary facts and figures, it gives policy makers and analysts enough information to analyse China's regional and global security and political roles. Two crucial aspects of the paper -- defence modernisation plan and defence budget -- have significant bearing on India, considering the political and economic rivalry between the two neighbours.

The Indian defence budget for FY 2006-07 is Rs 89, 000 crore (cr). This is 7.23 per cent more than the budget in FY 2004-05.

Taking the revised allocation of Rs 81, 700 at RE (Revised Estimate) stage in FY 2004-05, the increase is 8.94 per cent.
