You're saying that it's NOT OK for someone to criticize their own government? That's BS! That's our job- pay attention, look for problems and NOT hide heads in the sand. Criticizing the government IS NOT carrying water for a foreign leader- it's finding fault and making the fault(s) known.
Anyone who thinks the US isn't in a proxy war is oblivious- THIS is what Adam Schiff said-
Quoting a House impeachment inquiry witness, Schiff said: “The United States aids Ukraine and her people
so that we can fight Russia over there so we don’t have to fight Russia here.”

There's no end game, just 'to hand over weapons until someone gives up.
Make no mistake- we need to be very careful about how this goes because Russia wasn't made to give up their nukes- detente is great, but it's not the same when one side is ruled by someone who's crazy or wants to cause the other guy to flinch and at some point, I fully expect Biden to flinch or say something that causes a bad response.
Look for his comments about accommodating Russia if you want to see something that should frighten you.
