who can beat kakashi now...?

[slaton02]

Kakuzu, Tsunade, Bee, Raikage, and Kisame is debatable

how does he beat Kakuzu? I just don't see it at all.
Tsunade super healing and 1 hit k.o.
Bee maybe be debatable, would be a good fight but I see bee winning
How does he beat the 4th or 3rd raikage?
Kisame I see beating Kakashi, ninjutsu useless and kisame's is too powerful.
