Attack on Russia's nuclear deterrent requires severe retaliation.

 RUSSIAN DOCTRINE, ATTACK ON DETERRENT SAME AS NUCLEAR WAR

PUTIN IS WAITING FOR TRUMP'S CLARIFICATION

According to Russia's nuclear doctrine any attack on their nuclear deterrent is to be considered an attempt to weaken their response in a nuclear war, it requires a nuclear response. Putin made this clear in his conversation with Trump, but said, at this time, Russia is considering this attack as a  terrorist attack. This will be the case until he hears a clarification from Trump on the U.S. position or participation in this attack. Silence will most likely confirm that Trump and the U.S. participated and approved of this attack.

Most analysts believe that this attack was coordinated with Ukrainian actors, MI6 the CIA and possibly other intelligence agencies.

The question remains, did Trump know and approve, or was this attack done without his knowledge. If he approved, he will be on notice that any such attack in the future will be responded to as a nuclear attack. If he did not know, then there is deep trouble internally in the U.S., something that is already evident.

Considering Lindsey Graham's bluster in Kiev this weekend and some remarks by Trump, that if it was not for him, some bad things will happen to Russia, I expect somebody in the Trump administration knew about this.

As for now, we can expect a severe response on Ukraine, most likely a response far above what has been in the past. Russia has not yet attacked the bridges over the Dnieper or government buildings in Kiev. By declaring the Kiev government a terrorist government, Russia will consider those targets fair game. 

We can expect Trump will be notified by Russia as to their decision, although we will never hear of it. 

While Russia publicly considers Trump's efforts sincere, privately he is suspected of double dealing with Putin. a stupid good cop, bad cop attempt. If this is true, he will be in the same category with Starmer, Macron and the other NATO leaders. While negotiations will continue, his word will indeed be worthless, both with Russia and all those observing. While this may be the intent of those in the U.S. and NATO to undermine Trump, only actions by Trump can clarify what is true.

Trump may have a very small window to change this view.
