Why do people take what politicians or dictators say at face value? Of course, Putin will say that. Political statements are political statements.
Watch what people do rather than what they say, especially politicians and dictators. The Iranian rep was in Moscow and Putin told him things to console him.
In the end, Putin will do nothing. He has a war to fight. None of these leaders will help Iran. Why risk devestation to their own countries for a gaggle of mullahs?
Iranian leaders at this time are more interested in retaining power than enriching uranium, you can be sure.
Because they're not foreign policy experts, they're the type of people who think big-time wrasselin' is real.
