What you say is true about WWI and WWII. We have our JTF2 in Afghanistan with several confirmed straegic kills, but that seems to be about all we have right now. We disbanded our Airborne unit, we can't keep our helicopter's in the air, and we buy crappy ass used submarines that catch on fire on the way home.
I'm sure there have been improvements in the last few years, but being as self depreciating as we are, no one will ever know.
The Snow Birds are a great group of pilots, but you sure can't judge the state of our military from getting drunk with a few of them.
