War Theory #875?

Russia gather evidence that strikes from Ukraine in Russia are being done by non-Ukrainians, e.g. the U.K. and presents this evidence to the United Nations, declaring their right to retaliate.  Russia retaliates on the UK with a single strike using conventional weapons claiming this should not trigger NATO article 5 since it was a declared legal retaliation under the rules based international order. 

 We're close to worse than that if the west keeps pushing and inching forward. It's all bad on both/all sides.  

 Feels unlikely, too much Russian money parked in U.K. real estate. It’s seen as a safe haven. Bomb it and you remove that value prop., destroying far more in Putin’s and Russians wealth
