What happens if Russia breaks through the Line of Contact and Ukrainian discontent with Zelensky reaches full pitch? What does the West do? From Andrew Korybko at korybko.substack.com:

What’s regarded as the worst-case scenario from the perspective of the ruling Ukrainian elite and their Western masters is the best-case scenario for the rest of the world. In the event that Zelensky is deposed and peace talks immediately resume right as Russia breaks through the Line of Contact, then NATO might not feel as pressured by its security dilemma with Russia to conventionally intervene in Ukraine, thus reducing the risk of World War III by miscalculation.
The Ukrainian Intelligence Committee warned in a Telegram post about the worst-case scenario that could happen by June whereby a Russian breakthrough across the Line of Contact (LOC) merges with protests over conscription and Zelensky’s illegitimacy to deal a deathblow to the state. They predictably claimed that those protests, along with claims of growing fatigue inside Western and Ukrainian societies plus civil-military tensions in Kiev, are just “Russian disinformation” even though they all veritably exist.
“Zelensky Is Desperate To Preemptively Discredit Potentially Forthcoming Protests Against Him” and that’s why he claimed in late November that Russia is conspiring to orchestrate a so-called “Maidan 3” against him, which is what the Intelligence Committee explicitly referred to in their post. Their warning also came as Ukrainian media reported that Zelensky plans to ask the Constitutional Court to rule on holding elections during martial law in order to retain legitimacy after his term expires on 20 May.
The preceding hyperlinked report from Turkish media also mentions how “opposition party leaders Petro Poroshenko and Yulia Tymoshenko proposed forming a coalition government to avoid a crisis of legitimacy” but were rebuked by National Security Council chief Danilov. What’s so interesting about this proposal is that it was first tabled by an expert from the powerful Atlantic Council think tank in an article that they published in Politico in mid-December in order to serve that exact same purpose.
