The GDP is not the Budget, it is the Gross National Product. Our budget is sperate. The Defense Budget has been growing every year.
As the article points out we don't have the money for these expenditures and we are borrowing to pay for them. Also, they are not necessary and as Iraq and Afghanistan are proving, not practical. There is not a "threat" to justify such massive spending on weapons that don't address the real threats.
Also, our debt, our crumbling infrastructure, the loss of much of our manufacturing sector are a real threat as is our health care crises. Machines may replace some jobs but the US has lost a few million jobs to overseas production. The Auto Industry continues to close plants in the US and open them in Mexico and other countries.
Whether Automation or Globalization the jobs are gone and there are many people with skills and degrees that can't find decent pay jobs. Wages are down and barely keeping up with inflation. Workers have lost good paying jobs and now work for half or less. They are called under employed.
The talk of the Corporate Globalization apologists has been that the loss of these jobs will not effect the US but as we have seen it has.
Also, as the article points out, a lot of the Military Budget is hidden.
AlterNet: Going Bankrupt: Why the Debt Crisis Is America's Greatest Threat
http://www.alternet.org/stories/74620/It is virtually impossible to overstate the profligacy of what our government spends on the military. The Department of Defense's planned expenditures for fiscal year 2008 are larger than all other nations' military budgets combined. The supplementary budget to pay for the current wars in Iraq and Afghanistan, not part of the official defense budget, is itself larger than the combined military budgets of Russia and China. Defense-related spending for fiscal 2008 will exceed $1 trillion for the first time in history. The United States has become the largest single salesman of arms and munitions to other nations on Earth. Leaving out of account President Bush's two on-going wars, defense spending has doubled since the mid-1990s. The defense budget for fiscal 2008 is the largest since World War II.
Before we try to break down and analyze this gargantuan sum, there is one important caveat. Figures on defense spending are notoriously unreliable. The numbers released by the Congressional Reference Service and the Congressional Budget Office do not agree with each other. Robert Higgs, senior fellow for political economy at the Independent Institute, says: "A well-founded rule of thumb is to take the Pentagon's (always well publicized) basic budget total and double it." Even a cursory reading of newspaper articles about the Department of Defense will turn up major differences in statistics about its expenses. Some 30-40% of the defense budget is "black," meaning that these sections contain hidden expenditures for classified projects. There is no possible way to know what they include or whether their total amounts are accurate.
There are many reasons for this budgetary sleight-of-hand -- including a desire for secrecy on the part of the president, the secretary of defense, and the military-industrial complex -- but the chief one is that members of Congress, who profit enormously from defense jobs and pork-barrel projects in their districts, have a political interest in supporting the Department of Defense. In 1996, in an attempt to bring accounting standards within the executive branch somewhat closer to those of the civilian economy, Congress passed the Federal Financial Management Improvement Act. It required all federal agencies to hire outside auditors to review their books and release the results to the public. Neither the Department of Defense, nor the Department of Homeland Security has ever complied. Congress has complained, but not penalized either department for ignoring the law. The result is that all numbers released by the Pentagon should be regarded as suspect.
In discussing the fiscal 2008 defense budget, as released to the press on February 7, 2007, I have been guided by two experienced and reliable analysts: William D. Hartung of the New America Foundation's Arms and Security Initiative and Fred Kaplan, defense correspondent for Slate.org. They agree that the Department of Defense requested $481.4 billion for salaries, operations (except in Iraq and Afghanistan), and equipment. They also agree on a figure of $141.7 billion for the "supplemental" budget to fight the "global war on terrorism" -- that is, the two on-going wars that the general public may think are actually covered by the basic Pentagon budget. The Department of Defense also asked for an extra $93.4 billion to pay for hitherto unmentioned war costs in the remainder of 2007 and, most creatively, an additional "allowance" (a new term in defense budget documents) of $50 billion to be charged to fiscal year 2009. This comes to a total spending request by the Department of Defense of $766.5 billion.
But there is much more. In an attempt to disguise the true size of the American military empire, the government has long hidden major military-related expenditures in departments other than Defense. For example, $23.4 billion for the Department of Energy goes toward developing and maintaining nuclear warheads; and $25.3 billion in the Department of State budget is spent on foreign military assistance (primarily for Israel, Saudi Arabia, Bahrain, Kuwait, Oman, Qatar, the United Arab Republic, Egypt, and Pakistan). Another $1.03 billion outside the official Department of Defense budget is now needed for recruitment and reenlistment incentives for the overstretched U.S. military itself, up from a mere $174 million in 2003, the year the war in Iraq began. The Department of Veterans Affairs currently gets at least $75.7 billion, 50% of which goes for the long-term care of the grievously injured among the at least 28,870 soldiers so far wounded in Iraq and another 1,708 in Afghanistan. The amount is universally derided as inadequate. Another $46.4 billion goes to the Department of Homeland Security.
Missing as well from this compilation is $1.9 billion to the Department of Justice for the paramilitary activities of the FBI; $38.5 billion to the Department of the Treasury for the Military Retirement Fund; $7.6 billion for the military-related activities of the National Aeronautics and Space Administration; and well over $200 billion in interest for past debt-financed defense outlays. This brings U.S. spending for its military establishment during the current fiscal year (2008), conservatively calculated, to at least $1.1 trillion.
