It’s now how many countries you have, it’s what they bring to the party. We’re pretty much undermilitarized (less than 3% of GNP), overextended (all over the world, still in Kosovo, for example), and now have half of our conventional weapons depleted (due to the Neocon War in Ukraine).
The other countries are in worse shape.
Not to mention the $80,000,000,000 of materiel Brandon left behind in the middle of the night in Afghanistan.
