I think you (and the rest of US mil) often get the wrong end of the stick.
It's all about the money.
Just look at recent US military, shall we say lack of successes in the Middle East.
On a national level the cost is not about causalities but $'s .
And you could make no progress against such an unsophisticated enemy with all these weapons
Perhaps the latest advance will give you the edge? Stealthy refueling tankers, or some fancy drone might just be it?
Osprey is an amazing engineering system but I think a poor weapon of war
