There’s involved and involved. We should support Ukraine with material aid. Russia taking over would be a bad thing. But we shouldn’t send troops, and there will probably have to be a negotiated settlement, not a clear victory for one side or the other.
Most of that aid is either being given to US defense companies who then donate money to politicians who call for more weapons to be sent to Ukraine, or the weapons themselves are being sold on the black market. CBS did a documentary on this, but the deep state forced them to remove it. Why would that be I wonder?
