Once unthinkable in a time of two wars, Democrats and Republicans alike are insisting that the billions spent on the military can be significantly cut back over the next decade as the nation struggles to reduce its spiraling debt. Democratic Senate Majority Leader Harry Reid's plan to slash spending and increase the government's borrowing authority would cap spending by the Pentagon and other government agencies at $1.2 trillion. Conservative Sen. Tom Coburn has called for just over $1 trillion in defense cuts in his “Back in Black” plan, including fewer weapons, fighter jets and personnel. A bipartisan group of six senators envisions reductions of more than $800 billion in 10 years. The proposals reflect a rare bipartisan consensus driven by a dire economic outlook. The numbers even outpace what a Democratic commander in chief called for earlier this year. In April, President Barack Obama instructed the Pentagon to find $400 billion in defense savings over 12 years and said no decisions on specifics would be made until the Pentagon had completed a review of options for achieving such reductions. No matter which plan emerges in the latest debt showdown — Reid's or the House Republican plan by Speaker John Boehner — both call for creation of a 12-person, House-Senate bipartisan committee to find trillions in deficit cuts. Defense spending will be a ripe target, especially since the money would come from cuts in projected increases. Defense budgets, not including the costs of the wars in Iraq and Afghanistan, consistently have gone up in recent years, from just over $370 billion in the late 1990s to around $550 billion today.
