I suspect that this is going to have a similar effect on the tiny "resistance" movement as the nazi-Soviet Pact of 1939 or Khrushchev's Secret Speech in 1956 had in their time.
There will be a division between those who see this as the betrayal that it is and the true believers in Putin "the great strategist" who will stick to this line to the bitter end.
But it is the Russian reaction which is so totally disgusting: nothing, absolutely nothing. Unlike others, I have clearly said that it is not the Russian responsibility to “protect” Syria (or Iran) from the Israelis. But there is no doubt in my mind that Netanyahu has just publicly thumbed his nose at Putin and that Putin took it. For all my respect for Putin, this time he allowed Netanyahu to treat him just like Trump treated Macron. Except that in the case of Putin, he was so treated in his own capital. That makes it even worse.
The Skripals will most likely never be allowed to talk
“My darling sister, Yulia! You are not communicating with us, and we don’t know anything about you and Sergey Victorivich. I know that I have no right to interfere in your affairs without asking your permission, but I worry too much. I worry about you and your dad. I also worry about Nuar. [Nuar is Yulia Skrial’s dog, whom she left to stay at a kennel center, while she was traveling to the UK.] He is now at the dog hotel, and they want to get paid. We have to decide something what to do with him. I am ready to take him and to take care of him until you come back home. Besides Nuar, I am concerned about your apartment and your car. Nothing has been decided about their safety and maintenance. We can help with all that, but I need your power of attorney in my or my sister Lena’s name. If you think that all of these is important, draw up a power of attorney form in a Russian consulate in any country. If you won’t do that, we will understand and won’t interfere in your affairs.
