blame Russia for engadging in activities that warrants sanctioning
But why though? Russia had just observed 20 years of invasion of Afghanistan by the USA, with absolutely no divestment and no sanction as a result. So the logical conclusion should be that invasion doesn't warrant sanctioning. Why would Russia be a special case? If everyone can invade everyone, it would make sense that Russia understands that it also applies to them.
He should issue an arrest warrant for the leaders that threatened him too.
