Personally speaking I personally have no doubts whatsoever that we have no intention of invading Russia, having said that I wouldnt have been quite as sure had Clinton won. We as Nato have not enough conventional forces to launch an invasion of Russia, so thats another insurance policy against such silliness.
As for Putin I doubt he feels invasion is likely, he may feel threatened in other ways, but who knows maybe you should drop him an email and ask him?
One thing is for sure, as proved in history, political landscapes can change in a flash, as proved by the fall of the former Soviet Union, Yugoslavia, numerous places in the Middle East, Putin knows both the EU and Nato are facing an uncertain future and really has legitimate concerns regarding the Wests behaviours and deployments on Russias border....or do you think he is wrong?
