The EU and NATO will continue to write strongly worded letters to Putin telling him how naughty he is despite the Ukranian mess being of their making.
Putin will continue doing whatever he wants. Because he can and because the West can't stop him apart from throwing a nuke. Which we won't do as anyone with a working brain cell knows that throwing one nuke will cause a full theatre wide nuclear exchange and we'll all be ******.
This.
Putin will continue to push as much as he can and NATO/EU/UN will do nothing but moan and get some new sanctions against Russia. I think Putin would have to start a full scale invasion of eastern europe before there would be any major military response from anyone else.
