The conversation is in Russian, not Ukrainian. Here is my translation. The disputed (allegedly edited by FSB) phrase is in bold, and the version of Tymoshenko is in italic-underlined. My money is on that something third, mildly derogatory about Russians in Ukraine was said but there is no way of knowing now

Enjoy Ukrainian poltical thought

but mine is better

Shufrich (Shufrych): What happened with Crimea, I tell you, I'm certainly shocked. I'm shocked. Just today, I spoke to our friend. He was almost crying. I tell him: what will happen to us?
Tymoshenko: I myself am ready to take a machine gun now, you know, and go shoot this bastard in his forehead!
S: So I said yesterday, God forbids, a military conflict starts - I spoke at "Freedom of Speech " - I say, God forbids, a military conflict starts, I am a reserve officer and my eldest son is a reserve officer, we will take weapons and go to defend the country!
T: 100%. Listen, that is over top. Shit, we must take up arms and go waste these, shit, damned katsaps together with their leader!
S: I am telling you...
T: Pity I can not be there. And that I was not in charge of all these processes: f*ck would they get Crimea!
S: Well, you know, I too, by the way, thought about it. If yoy'd been here, then, maybe, this would not have happened. But we did not have any military potential. But something they just, you know, and the most upsetting...
T: I would find how to waste these fuckers! And I hope I will use all my connections, I will engage the whole world, as soon as I can, so that, shit, there is not even a burned field left out of Russia!
S: Well, listen, here I'm your ally, not just an ally. Listen, we talked about this today, this morning was a meeting of leaders of factions and I spoke with Victor. Victor says, now what should the remaining eight million Russian do, those who remained in Ukraine? They're pariahs!
T (transcript, allegedly fake): Shit, shoot them with nuclear weapons!
T (tweeter, allegedly true): Russians in Ukraine are Ukrainians
S: Well, I cannot argue with you, listen, because what happened is, indeed, a horror. But here is an option, because today all their actions are definitely illegal. We have to defeat these illegal actions in some judicial international way.
T: Sure, we are going to Hague International Criminal Court!
