Today, we are once again being told that this global strategy needs to give way to a more restrained and modest approach, even though the indebtedness crisis that we face in coming years is not caused by the present, largely successful global strategy.
Of course it is precisely the success of that strategy that is taken for granted. The enormous benefits that this strategy has provided, including the financial benefits, somehow never appear on the ledger. They should. We might begin by asking about the global security order that the United States has sustained since Word War II—the prevention of major war, the support of an open trading system, and promotion of the liberal principles of free markets and free government. How much is that order worth? What would be the cost of its collapse or transformation into another type of order?
Whatever the nature of the current economic difficulties, the past six decades have seen a greater increase in global prosperity than any time in human history. Hundreds of millions have been lifted out of poverty. Once-backward nations have become economic dynamos. And the American economy, though suffering ups and downs throughout this period, has on the whole benefited immensely from this international order. One price of this success has been maintaining a sufficient military capacity to provide the essential security underpinnings of this order. But has the price not been worth it? In the first half of the 20th century, the United States found itself engaged in two world wars. In the second half, this global American strategy helped produce a peaceful end to the great-power struggle of the Cold War and then 20 more years of great-power peace. Looked at coldly, simply in terms of dollars and cents, the benefits of that strategy far outweigh the costs.
You can argue that the "Pax Americana" that we've paid for isn't worth the price we've paid. But at least admit that if you pull the "Americana" part out, the "pax" will fail more regularly. Explain to me how we profit by that?
