Not China, not Russia, not North Korea, not Iran, not terrorists...According to Admiral Mike Mullen, the Chairman of the Joint Chiefs of Staff, the "single biggest threat" to American national security is the US national debt, which is either $8.85 trillion (public debt), $13.4 trillion (total national debt), $20 trillion (total debt including GSE debt), or $124 trillion (total debt including unfunded obligations), depending on one's definition of the word "debt." And as Zero Hedge has long been warning, the imminent increase in interest rates (sooner or later), will eventually put the country in an untenable funding position. "Tax payers will be paying around $600 billion in interest on the national debt by 2012, the chairman told students and local leaders in Detroit." The Chairman (the real one, not his pale imitation over at Marriner Eccles) politely forgot to add that the successful rolling of nearly $600 billion in debt per month is likely an even greater threat to national security.
