My own take is that the underlying agenda here is to unseat the Middle East in terms of power.   Seeing Trump's comments in the past and Putin's comments in the past, they both regard  it with contempt.  Putin has a big issue with the terrorism on his doorstep, both from the Middle East and pawns like Chechnya.  Even more so than does the U.S.A.  If you look at the oil situation here in North America now, and  also consider the possibility that Venezuela can be redeemed economically and politically, and add to that the might of Russia's oil producing capacity, an interesting opportunity presents itself.   That being an embargo on Middle East states who promote terrorism both by funding and political ties.  We could not have done that two decades ago, now perhaps we can.   The world managed to turn South Africa from apartheid in the 90's.  It would be a wonderful thing for this world if Islamic terrorism faced the same fate as apartheid.
