A couple willing ones I could think of would be Sand and Lightning. Sand because their Kazekage owes his life to Konoha now(plus their recent history), and Lightning because they already introduced the current Raikage and Killer Bee, plus some subordinates. Probably the subordinates will report back to HQ if they see the devastation here and maybe we'll see some support from either of those villages later. They have a common enemy in Akatsuki, anyway-Team Hawk was sporting the red cloud robes when they fought Killer Bee, so as far as Lightning is concerned the Killer Bee kidnapping was Akatsuki's fault.
They NAILED Naruto's return, man. I was happy to see it. I stopped reading the manga shortly after this next fight's conclusion, I wanted the aftermath to be a surprise to me.
