Maybe I'm an amateur.

Maybe this is a very amateurish thing to say, but here it is.

If Europe is going to give money to Iran, then Europe had better not continue to criticize the United States for refusing to accept refugees from the Syrian civil war which Europe also failed to prevent or to stop.  Assad needs to leave.  There's no other acceptable resolution.   

I can't believe that there's even speculation that the Iranian government is going get a credit line from extorting Europe with threats, while the democratically elected government of Venezuela is waiting to be slaughtered by a dictator.
