How Much Defense Spending Is Enough?

'It is unrealistic to imagine a return to long-term prosperity if we face instability around the globe because of a hollowed-out U.S. military lacking the size and strength to defend American interests around the world.

Global prosperity requires commerce and trade, and this requires peace. But the peace does not keep itself. The Global Trends 2025 report, which reflects the consensus of the U.S. intelligence community, anticipates the rise of new powersâ??some hostileâ??and projects a demand for continued American military power. Meanwhile we face many nonstate threats such as terrorism, and piracy in sea lanes around the world. Strength, not weakness, brings the true peace dividend in a global economy.

We have not done enough to help our military preserve the peace and deter (and if necessary, defeat) our enemies. Americans have fought superbly in Iraq and Afghanistan, and have prevented any further terrorist attacks on the scale of 9/11. But faced with a nuclear Iran, or a Chinese People's Liberation Army that can deny access to U.S. ships or aircraft in the Asian-Pacific region, there are many missions ahead.

Yet we face those challenges with a baseline defense budgetâ??defense spending minus the cost of the warsâ??that is 3.6% of GDP, significantly less than the Reagan-era peak of 6.2%. Our active-duty military is two-thirds its size in the 1980s. - Brooks, Deulner, & Kristol

'

Ben and Drezner have tackled this op-ed already but to add my own two cents, I think some perspective is in order:

'Between June 2007 and November 2008, Americans lost an estimated average of more than a quarter of their collective net worth. By early November 2008, a broad U.S. stock index the S&P 500, was down 45% from its 2007 high. Housing prices had dropped 20% from their 2006 peak, with futures markets signaling a 30-35% potential drop. Total home equity in the United States, which was valued at $13 trillion at its peak in 2006, had dropped to $8.8 trillion by mid-2008 and was still falling in late 2008. Total retirement assets, Americans' second-largest household asset, dropped by 22%, from $10.3 trillion in 2006 to $8 trillion in mid-2008. During the same period, savings and investment assets (apart from retirement savings) lost $1.2 trillion and pension assets lost $1.3 trillion. Taken together, these losses total a staggering $8.3 trillion. Since peaking in the second quarter of 2007, household wealth is down $14 trillion.'

So yes, Brooks, Kristol, et. al. are right, there are threats to global commerce. But they overwhelmingly stem from the world's parliaments, central banks, debt-strapped consumers, and financial markets. The People's Liberation Navy and Somali pirates? Not so much.
