Actually, General Myers is an Air Force general. I remember back when he commanded US Space Command.
My amateur opinion says we'd be hard pressed to occupy another country with Army or Marines.
As for the Air Force and Navy: logistically we're working a lot harder than you think. On the other hand, we could launch some pretty massive strategic attacks using conventional weapons. Cruise missiles from ships and B-52s, as well as B-2s which can hit a dozen separate targets using 2000 lb JDAMs. For attacking dug-in forces in the field or enemy air bases, a single B-2 can drop 80 (that's right, eighty) 500 lb GPS guided bombs, each one with a CEP (Circular Error Probable) of 10 feet.
We couldn't stop genocide or fight house to house, but we could lay waste to a nation, its infrastructure and military.
Of course, rumor has it the USAF is going to cut flying hours by 40% following the BRAC announcement. We don't have enough cash to keep 'em flying and maintained at the same time.
As an anecdote, my last unit cut the large majority of funding for all TDYs. Only the most necessary TDYs were approved, but only after review by the Ops Group commander.
What unit are you with and whats your AFSC?
I'm currently in tech. school at Goodfellow with the 315TRS.
The drop bomb crowds are not paying attention to history. Our next near term competitor is China. Were are we going to be flying from to get there to drop bombs? And for how long? We did not have enough munitions for Iraq, a small country compared to china.
You only win wars with boots on the ground. Anyone that thinks we are going to nuke them till they glow needs to put down the crack pipe.
We do not have the troops to fight two land wars.
And the gear is currently in Iraq, it is functioning, but beat up.
Meyers downplayed the situation.
We will be out of Iraq sooner based on the recruiting issues it is causing.
But on the flip side first term enlistments are at an all time high.
