'enemies of Russia'
The biggest enemy of Russia is the enemy of the rest of the planet as well - Vladimir Putin.
Yes we have other enemies but only one is sending tanks at us at present so he qualifies as the biggest problem at present.
Putin is the one who is sending young people to their deaths attacking another country. Putin is the person whose friends have made huge fortunes off the Russian people. He is their enemy. At the moment, only small numbers of very brave people are protesting about it. In the future???
