The Iraqi Army have again claimed that they have downed aircraft from the US led coalition that was providing military assistance to ISIS.
According to a report by the Iranian Fars News Agency (see below) a US helicopter carrying arms to ISIS was shot down on Thursday.
A few days earlier on Monday it was also reported that the Iraqi army had downed two British planes delivering weapons to ISIS.
I would say there are historical grounds for being suspicious, but there's no smoking-gun evidence in that article.
What I would like to see is the percentage of total airdrops that have been dropped in IS controlled territory. If it is extremely low, then that would lend credence to the US claim that those very few drops were errors.
If the US were to want the war against IS to drag out very long, the percentage of drops falling into IS hands would have to be probably 30%, depending upon IS's other sources of weapons. In addition, besides just airdrops, one would have to factor in non-airdropped aid to Iraq and the Kurds, such as by cargo planes and ships that land and dock.
It is not farfetched to think that the US, knowing that it did the vast majority of the fighting in Iraq (rightly or wrongly) before, doesn't want to repeat that error. The US trained and heavily equipped the Shiites in Iraq only to see them drop and abandon their advanced weapons and equipment at the first sign of a very tiny (in relative terms) ISIS group roll right at them in non-armored vehicles. Why didn't those Shiites stand and fight the ISIS when it was no more than 5-7 thousand? The Shiites hugely outnumbered those Sunnis and had all the weapons and ammunition and equipment to defeat ISIS right then and there, and more weapons and ammo, etc., would have been forthcoming from the US had those Shiites have done that.
So, to have the Shiites of Iran making the claims they have in the linked article is telling half-truths at best. Propaganda spin works on both sides, comes from both sides.
The Iranians want the US to simply unleash whatever it would take for the US to completely wipe out IS in a month, but that wouldn't create the situation where Shiites defend themselves but rather rely upon the US taxpayers to defend them.
I'm not saying I support US actions in the Middle East. I don't. I know that the US foreign policy toward the region has been stupid even in secular terms and going back nearly to the very first time the US engaged the area.
