I'm not sure people are understanding what's been said. Iran has admitted that they did it albeit not intentionally. Javad Sarif Foreign Minister stated,
A sad day. Preliminary conclusions of internal investigation by Armed Forces:
Human error at time of crisis caused by US adventurism led to disaster
Our profound regrets, apologies and condolences to our people, to the families of all victims, and to other affected nations.
Interesting he used U.S. Democratic politicians talking points of blaming the US by saying "US adventurism led to disaster" As for me I'll never believe he dreamed up even saying it this way without being aware of what was being said in the U.S. by Trump's critics. It's just not an ordinary response when one wants to fess up to something. So this crazy and insane charge is being used by them to saved face.....it's the U.S. President's fault.....No mention of their people negating the first rule of engagement and that is to properly identify your target before taking action. As apologies go it comes across as offensive. Should a heart felt apology bring in other parties to condemn? I'd say not. It just admits what YOU DID WRONG and allows others to make those other assessments.
