US Secretary of State Antony Blinken hinted on Wednesday that Ukrainian forces could bomb Russia with military materiel supplied by the US, something they had previously been forbidden from doing.
I think when a senior official like this says something, it's pretty close to being policy. It's kind of like a "soft launch" of the policy. He wouldn't have said it if the US didn't plan on going through with it.
When the United States Secretary of State says words like these, they have real meaning. This is not you and I shooting the bull over policy, this is the highest level of diplomacy in America speaking.
You may not have heard it, but Russia got the message loud and clear.
