From Charles Krauthammer:
In the end: 10 years, no second attack (which everyone assumed would come within months). That testifies to the other great achievement of the decade: the defensive anti-terror apparatus hastily constructed from scratch after 9/11 by President Bush, and then continued by President Obama. Continued why? Because it worked. It kept us safe — the warrantless wiretaps, the Patriot Act, extraordinary rendition, preventive detention and, yes, Guantanamo.
Perhaps, says the new conventional wisdom, but these exertions have bankrupted the country and led to our current mood of despair and decline.
Rubbish. The total cost of “the two wars” is $1.3 trillion. That’s less than 1/11th of the national debt, less than one year of Obama deficit spending. During the golden Eisenhower 1950s of robust economic growth averaging 5 percent annually, defense spending was 11 percent of GDP and 60 percent of the federal budget. Today, defense spending is 5 percent of GDP and 20 percent of the budget. So much for imperial overstretch.
