From "The Analyst":

KHARKIV FRONT ISN’T DOING SO WELL

My contacts are telling me this afternoon that the Kharkiv front is not as stable as Ukraine is claiming and that the Russians are behaving in a random way that’s making it difficult to determine how to deploy defenders. Without knowing what the Russian objective is, (I presume the worst, as they repeatedly stated in endless conversation on state TV, the aim is to reduce Kharkiv to rubble), the forces available to Ukraine are struggling to contain the situation. Four more border settlements have been reported as captured and confirmed as such.
I don’t think Russia has the forces to make it all the way to Kharkiv, but I do wonder is they’re trying to push closer to bringing more artillery to bare and cause as much mayhem as they can, while stopping any more of those ludicrous cross border raids that drew their attention to the area so effectively. Either way, when the Ukrainians say things are ‘difficult’ that’s an almost British level of understatement.
