Meh. She's been slowly getting more and more unhinged over the last ~2 years and wasn't starting from a good place to begin with. Anyone who champions trading territory for an unenforceable ceasefire, and holding an election that couldn't pass a constitutional challenge for it's legality, has lost the plot.
She went on a whole media campaign ~18 months ago doomsaying about how bad this was going to go if Ukraine didn't immediately find the willingness to negotiate on Putin's terms, and be willing to make territorial concessions just for a ceasefire and her doomsaying has proven to just be wrong. She claimed Ukraine was on the precipice of collapse, obviously not true.
Her credibility here, fwiw, almost entirely comes from the fact that she was Zelensky's press secretary prior to the start of the war. She was a bit of a wing nut before the appointment (she ran with the Hunter Biden/Burisma story years back despite there being little to nothing there) and her interviewing with Tucker now tells us a lot of where she's at these days.
