"Is there any actual US policy to get Russia to accept a ceasefire? Or is the US is an ally of Russian imperialism?"

"Ukraine has proposed a ceasefire without conditions. Russia will almost certainly reject this and try to dictate to [US Special Envoy Steve] Witkoff that the US help Russia achieve colonial control of Ukraine, something that Russia could never achieve on its own.
    "Then we see if there is any actual US policy to get Russia to do what Ukraine has done, to accept a ceasefire, or if the US is an ally of Russian imperialism and this whole process has just been a cover story for American submission to Russian wishes. If Witkoff comes back from Russia endorsing Russian demands regarding Ukrainian sovereignty we have our answer.
    "Russia has no more right to dictate anything that happens inside Ukraine than Ukraine has to dictate what happens inside Russia. And the 'root causes' of this war are all inside Russia, as the Russians are reminding us."
