US Slams Strikes on Russia Oil Refineries as Risk to Oil Markets

They don't want this war. It's too close and too big for comfort. It might escalate into a real war with real consequences for USA and Western Europe.

They do want to make it costly and painfull for Russia, with Ukraine as proxy, but without risking much themselves.

Russia knows this so tries to make western involvement seem bigger than it is. Not to fight the west, but to scare it in backing off.

The west wants to help more, but without too much effort, and needs to deal with its own people pushing both more and less involvement.

So here we see the USA trying to cool things down. I presume they see the Israel thing cool down enough to start delivering to Ukraine again, and are preparing for it.
