They question you're really asking is "why is the war taking so long?"
Because it's a war.
look, if someone looks like they are losing a war in the beginning, middle and the end act of it, I wouldn’t have much faith that extending it is the best solution to finally win.
I think he is asking how well the devastating sanctions have been working so far. Which is a retorical question of course, because obviously they haven't harmed Russia all that much. Actually, they are hurting the EU as well because of the risen energy prices.
