S.H.I.E.L.D. or H.A.M.M.E.R.?
I can see a return to S.H.I.E.L.D. easy enough, but changing the letterheads and stationary back again is going to cost another Billion Dollars the US Government doesn't have... Don't even get me started about the uniforms? Did they recycle the last ones into some sort of womb or just dump a hundred thousand blue bulletproof fatigues on the door step of the salvation army? If the all the Bums and hobos were bullet proof, that would change the pecking order on the streets some what, wouldn't it?
More likely they were probably sold to some third world dictatorship who is going to cause problems down the line, if Steve doesn't buy them back at a substantial loss since it's hardly fair to talk about escrow to countries without paved roads or (even) 20th century healthcare, that maybe Steve would want to lose money on any such deal if he could suggest where these monies be spent instead of an aggressive military bent on a warfooting because of Norman osborn's on pressurings before hand?
