I'm afraid the US Government knows the answer to that all too well.
The question then becomes why the US Government hasn't shouted the answer from the rooftops since day one of the war?
Because WE WOULDN'T LET THEM. Our troops stood at the border while the Russian CONVOYS were going from AQQ to Syria.
They were held there by the UN and the DEMOCRATS, who BEGGED TO GIVE SADDAM MORE TIME TO COMPLY, So we wouldn't have to attack.
This was just one set of criminals, covering for another, and the US PUBLIC (part of it, anyway) was duped into helping.
The FACT the Russians were carting this stuff to SYRIA was ANNOUNCED in NEWSPAPERS WORLDWIDE.
The Russian CONVOY (one of many) near the end of the removal process, was attacked in a cross fire situation. THAT WAS IN THE NEWS.
WHERE the Russians TOOK THIS STUFF, was in the News. (I have pictures, wanne see 'em?)
It's OUR SHORTTERM memory that allows the DEMS and MSM to get away with this stuff.
I'll prove it.
There was an issue over the missing POW's in Vietnam after the war. A SENATE committee was formed, investigated, came back and said, "FOREIGN GOVTS ASSURE US THERE ARE NO POW'S IN PRISON CAMPS".
Question #1: There were two movies made about a guy that goes back to VIETNAM to rescue these POW's, that were supposedly non-existant. Name the two movies and the main stars.
Question #2: What SENATOR was CHAIRMAN of that committee? (In real life, and in the movie)
