When I met General Sada, he seemed pretty credible. Perhaps you know him better.
All we can say about Sada is that he claims a pilot he knows (and does not name) told him this story. In other words it is second hand hearsay evidence. He asks us to trust him and trust that his friend is credible.
I am sorry for not trusting anyone in Iraq and for being skeptical of a high ranking member of Saddam's Baathist officer corp.
In anycase this should be easy to prove - we had a no fly zone in Iraq that cut off flights into Syria from Iraq and we were monitoring Iraq via AWACS and satellites like no other country.
Easy enough to see if any such flights took place.
That no one in this administration has touched it means that
A) This story is not credible.
or if true like you think
B) This admin is covering up their gross incompetance for letting dangerous WMD get away. I don't think this is the case of course.
