“These Russian soldiers are in the Transnistria Region which has an ethnic Russian population in the hundreds of thousands.”
So what? There are millions of ethnic Mexicans in the US. Does that give Mexico the right to invade the US?
Moslems have a dictum that wherever a moslem lives, that place is islamic. Russia has millions of moslems. Does that give the islamic states the right to invade Russia?
” Does that give Mexico the right to invade the US? “
It is currently happening, with no-one doing anything about it, so I guess it does.
