Tit for tat finger pointing and posturing is going to result in only one outcome for Ukraine.
That outcome is realization by Russia that they are never going to end the war by negotiation and that their only option is to try end the war soonest by winning it.
The really disturbing thing about the trajectory of the Trump Administration's attempts to mediate a negotiated peace is the plain fact that the Zelensky government, EU/NATO backers of the Zelensky regime and their now out of power Uni Party allies in the US Government all seem to be trying to back Putin into a corner where his only viable option is to pursue a major military operation to try to bring the war to a close by decisively defeating the Ukrainian opposition.
Once this happens, the pressure for the Trump Administion to intervene to try to prevent the Russians from winning or be reviled to stick the blame on President Trump as the President who lost Ukraine will become unrelenting.
Ukraine is not going to give up. This war can easily last for another 10 years. Unlikely we'll see massive battles such as Bakhmut and Avdiivka. Instead both armies will be entrenched and it will be mostly drones and artillery. The war will be fought at a lower intensity.
The window is closing for a ceasefire. Trump wants it to happen by Easter.
