True cost of US debt | Niall Ferguson

Ferguson’s Law states that any great power that spends more on debt service (interest payments on the national debt) than on defense will not stay great for very long. True of Hapsburg Spain, true of ancien régime France, true of the Ottoman Empire, true of the British Empire, this law is about to be put to the test by the US beginning this very year, when (according to the CBO) net interest outlays will be 3.1% of GDP, defense spending 3.0%.
