We are out of Iron

I have always liked the famous Bismarck quote about diplomacy and force - "The great questions of the day will not be decided by speeches and resolutions of majorities - that was the mistake of 1848 and 1849 - but by iron and blood."

Which leads to the United State's current problem, we are running out of men and tanks to shuttle around the world to scare people. Shame, we might actually have to use diplomacy in the future.

"These moves seemed like perfectly logical geopolitical responses to heightened dangers. But they also helped mask another reality. Because the military today does not have enough available ground troops to use for intimidation, the moves were pretty much the only options rather than choices among several."
