Sanctions imposed on Russia should be effective!

I understand that Russia must make $70 a barrel in order to remain solvent.  Russia needs money!.

I understand, too, that there's a rumble among certain political factions such that, if Russia continues an aggressive policy, it will lead to an exodus of a significant number of Russians from Russia.  

I further understand that many several independent states in the Russian Federation are hostile to the expansion of the Russian state.

There is, after all, a vigorous fractious polity in the Russian Federation, today.
