As @Cherico said.You have russians in your country? you are hurting them,then,and soviet army must liberate you from your washmachine and other things.
It do not matter what host think.Important thing is,what kgbstan think.
And they think,that they could use russian-speaking minority as pretext to invade.
And Latvia would get rid only of those who support Putin,not all russian speaking citizens.
No kgbstan invasion.
Becouse putin use long dead russian nation as pretext to invade other countries.You have russian speaking minority? wait for kgbstan tanks.
Better get rid of themm when kgbstan tanks are on Uraine,becouse later it would be,well...too late.
They certainly tried - but american soldiers do not mass raped and murdered locals for their washing machines.You could not support that,even with big bribe.
russians are ruled by KGB,who do not care about their fate.So,banning average russian joe mean nothing.But banning members of KGB mafia who rule there - it would work,if could be done.
