So.. assuming it is "true" (and if you take at face value anything Ukraine or Russia says you are an idiot) and we apply your idea of penalties, are you also willing to apply those to western nations (ie, US, UK, France, etc...) who have use air assets to bomb other countries, sent special forces into another country (invasion!), sent military "advisors" to help rebels/"freedom fighters", etc? Or shall we just ignore the hypocrisy of it all?
Can only imagine if Ukraine were some country bordering on the US/UK/France/Germany and a similar unstable political situation existed which was at least in part fostered by Russian political meddling (as opposed to Western in Ukraine). The tanks and planes would have rolled the border long ago.
