Here is a reason to send ATACMS to Ukraine and perhaps even cruise missiles. I dunno why they don't take out those 10 rail entrances into Ukraine, that are probably less than a half dozen now, since they recaptured the rest to the border or close. This kind of weapon with this kind of range should warrant an appropriate response. Take out the rail bridges 100km or so inside Russia on the rail routes to Ukraine with the missiles, trap the Russians in Ukraine and cut them off from supply and also trap the conscripts inside Russia unless they march into Ukraine. Either do it with missiles, special forces, or destroy and suppress the local air defense and do it with aviation. Use the missile for retaliation on electrical substations or rail infrastructure, tit for tat.
If this is gonna be a proxy war with Iran, Russia is gonna lose, these are IRBMs and rate patriot systems in response. So, the Saudi's can pay for them with their $400 billion gift to Ukraine and move behind them in line for them. Since Iran lined up on the side of Russia, the Saudi's will have trouble not playing ball. The oil price rise was about Biden and the heat he's putting on MBS for murder and other bullshit and is an attempt to fuck with the election, a hostile act, just as much as when the Russians did it. He had better hope the democrats don't win, or the CIA might arrange for his rather extended family to chop the fuckers head off, or blow it off, whatever works.
