President Biden may not, but Fed certainly is. Remember with the eurodollar system, Fed's role at this point is pretty much a liquidity provider for anyone and everyone which they did with unconditional access to swap lines etc. since April 2020 injecting trillions of dollars of liquidity into the system. The inflation we are seeing right now is largely a by-product of that. Fed with its utterly irresponsible course of acts over the past two years is directly responsible for this crisis. Their choice at this point is doomed to crash the US economy with recession if they want to do anything measurable to fight inflation. Which if they end up doing, will largely invalidate their mandate of full employment and thus the validity of their existence.

With regards to President Biden, he will have to be held responsible for applying all out sanctions which have not been able to achieve their objectives. If the goal of the sanctions was to stop the war, that has not happened in last 45 days. We don't know how difficult life has been for the average Joe in Russia from those sanction bites due to the censorship in media in both west and Russia. It certainly has however affected the life of the average Joe here and not for good. But, we are told this is at the expense of our moral victory.
