There is a zero-sum game at the heart of the budgetary process: even if rates stay low, recurrent deficits and debt accumulation mean that interest payments consume a rising proportion of tax revenue. And military expenditure is the item most likely to be squeezed to compensate because, unlike mandatory entitlements (social security, Medicaid and Medicare), defence spending is discretionary.
It is, in other words, a pre-programmed reality of US fiscal policy today that the resources available to the Department of Defense will be reduced in the years to come. Indeed, by my reckoning, it is quite likely that the US could be spending more on interest payments than on defence within the next decade.
And remember: half the federal debt in public hands is in the hands of foreign creditors. Of that, a fifth (22 per cent) is held by the monetary authorities of the People’s Republic of China, down from 27 per cent in July last year. It may not have escaped your notice that China now has the second-largest economy in the world and is almost certain to be the US’s principal strategic rival in the 21st century, particularly in the Asia-Pacific. Quietly, discreetly, the Chinese are reducing their exposure to US Treasuries. Perhaps they have noticed what the rest of the world’s investors pretend not to see: that the US is on a completely unsustainable fiscal course, with no apparent political means of self-correcting. That has profound implications not only for the US but also for all countries that have come to rely on it, directly or indirectly, for their security.
