Sorry, I never said 'it's not important': I'm trying to find out - and to explain - how do the Ukrainians and Russians see the situation, what is influencing them to do what they do, and what are they doing (as result).

As about:

- 'they can only go to Lysychansk'; please read my summary.

- once again: what somebody else says, sorry, not my issue. I'm reporting what I happen to be informed about.

Finally, nowhere did I say anything even distantly similar to, 'operation was a success if 15000 Ukrainians will be surrounded'.

That's a brazen 'putting words into my mouth': I dislike this very much and would recommend you to stop doing this right away. Otherwise, I'll simply block you.
