I think your probably right.
I would guess that after the attack on Tony's home everyone thinks his dead.
Tony goes underground unsure of who to trust (the talk of villians who's power reaches everywhere means the Mandarin's Ten Rings terrorists or AIM might have agents that infiltrated the U.S Air force or Stark International or Shield).
It fits with the back to basics Tony on his own idea.
With everyone thinking Iron Man/Tony Stark is dead it would give the military even more of a reason to push Rhodey as War Machine as Iron Man in not around to save/defend the earth.
