Wars are always caused by the people who run Governments. You could have a holiday in places like China & Russia & find their people helpful & friendly towards us. Governments are the problem.
Our so called leaders should go out of the way and make friends with Russia. Common sense isnt it?
Russia has became an enemy because when NATO was created after WW2 Russia was excluded which obviously upset them and we cant blame them. Why was that because no one wants to be excluded from a club.
Putin has nothing to lose so it would definitely end up with Nuclear Weapons.
