Doing business in Russia or anywhere else where the rule of law comes down to the wishes of one or two men is a fools errand. One US company after another has been ripped off by the oligarchs in Putin's orbit with no recourse but to agree to whatever new terms have been set. Pres. Clinton, both Bushes and Obama all thought they could deal with these people on the basis of common interests,international and national laws. Yeltsin and even more so Putin made them all look foolish. Now we have yet again another President on tap who thinks he can smooze these thugs.  At this point I can only hope Congress holds Tillerson's feet to the fire on these points and refuses to allow Trump to trade business concessions for the security of our allies in Europe.
