Just like easy cheesy Albanese, still no valid answers in sight.
If and when you stop assuming that Ukraine was non-threatening you'll then realise your silly question was actually invalid. Mr Putin's necessary military operation was due to the ramping up of insulting belligerent Ukrainian behaviour and the over-the-top military arming of a bunch of thugs during what was peace time. Just know that when NATO/U.S & the bootlicking allies pull the trigger on the Russian forces, this Russian military operation will then become a full blown war against the lot of them and I'm just guessing out loud that Vlad's big red button is all warmed up and ready to press.
