Yes. Kai is Hitler.
And I'm not gonna lie, Kyuu's thinking process has basically been my mindset the whole time.
Even with an army of highly skilled shinobi, the Mist would get thrashed.
You used Nazi Germany as a reference? That scenario plays out quite a bit different than your brief, "there small but mighty" statement above.
Germany had some advantages that the Mist don't.
Its the reason Shen's secret mist plans don't worry me. Because if the Mist somehow managed to rule all and become a monopoly, I, and likely a few others, would call him on that bullshit.
Buuuu potential war aside, I don't care who the Kage is, Katsuo will still give each of you a hard time once in office.
Edit: All this reminds me. The fact that the Mist invaded the Land of Fire with absolute ease pisses me off.
