This doesn't make sense to me - it wasn't a secret that iran might do something in retaliation, and if i remember right, they gave advanced notice to iraq about their balistic missiles (which surely leaked to usa). I'm not sure what they would actually conceal by doing this.
Specific timing?
^^
I'm not sure how - the misile strike happened before the passenger plane was shot down. You can't hide the timing after the event happened.
Yeah, but I assume if Iran suddenly closed their airspace, it would give Iraq/US forces a pretty big signal the attack is imminent.
The US could preemptively attack Iranian bases.
This title is entirely nonsensical.
So Canada has a recording of a guy who was not responsible for the situation on the day the downing happened, making a "What if we had done X" speculation - in the form of a question.
