President Obama and his State Department are insisting there is no contradiction whatever between supporting Sunni rebels in Syria and fighting them in Iraq.
The key safeguard is the "careful vetting."
As Mr. Kerry has shown repeatedly, the US is incisive in sorting through who is doing what in these two regions (and elsewhere, as with Ukraine), and what is going on.
Everything is kept straight via the use of drones, the latest theories from the Robert Kagan Institute, and assorted surveillance equipment.
First, this Syria mission involves carefully vetting the good guys on the ground. These are mainly FSA (Free Syrian Army), comprised of ex-Assad soldiers and citizens who only want democracy.
True, many of these citizens also did recently vote for Assad as the lesser evil vs. ISIS.
Above all, carefully vetting these good guys must be done properly, and Mr. Kerry has stated he will personally lead the way.
He will enter Syria with his flak jacket and direct the sign-up stations where the money will be handed out in packets.
This will mean ascertaining who is ISIS, who Jabhat al-Nusra, who al-Qaeda etc. and turning those particular gentlemen away with a "Thank you, but not at this time" response.
The "Good jihadis! Come here for your money!" stations in Syria will also issue a contract to each fighter carefully vetted.
This contract will require 1) that no US weapons that happen to come their way can be sold to ISIS. Doing so will lead to severe fines (giving back the money) and possible imprisonment from US marshals who happen to be in the vicinity.
It will require 2) that any certified and vetted FSA freedom fighter against Assad cannot, and will not, continue that fight against Shias in general by moving across the border into Iraq to fight against Maliki.
Mr. Kerry will personally oversee the oath ceremony by which each carefully vetted fighter in the struggle against Mr. Assad will be verified and given a portion of the 500 million.
Now, any FSA type jihadists who got the money and who cross over into Iraq, due to their enthusiasm to not only fight Assad but his buddy Maliki in Iraq, will be subject to imprisonment in Iraq jails guarded by Shia militia.
In the past week these Shia have tended to shoot all Sunni prisoners versus guarding them or risk having them liberated to fight for ISIS.
All these conditions are clearly stated in the contract for this carefully vetted aid money, which each rebel must sign.
Also, the rules are laid out in large print on a billboard, very visible, outside each recruiting station.
