The same day that NP flew commercial out of DC, Lavrov gave Germany permission to monitor the Kerch Strait. Now the DS, of which NP is part, has attacked Russia in the Kerch Strait. Coincidence? Who has a submarine in the vicinity? I bet Putin is researching that right now. This may not be the straw that broke the camel's back (Putin's forbearance), but if not, then we're only one away.
