Didn't we have a whole impeachment about a president preventing arms that were allocated by Congress from going to their destination? Oh yeah that was Trump trying to get some election fuckery from Ukraine. Granted, the election aspect was another level on it but that is functionally the same thing you're demanding Biden do which was already determined to not be ok. President doesn't have that power so maybe instead of wondering why Biden isn't fixing the thing all on his own, we can start (or continue if you were ever paying attention between presidential elections) pressuring and replacing the Congress critters that are actually approving the sale of arms to continue the genocide. Why does everyone keep getting big man deluded when we know for a fact that the president isn't a king with total control?
