You put lots of effort into the article and I commend you for your thoughtful composition, but...
It appears that "history" is your hot button. In all honesty it doesn't appear the President was trying to impress his local audience with his knowledge of the history of warfare.
In my view he was attempting to reach a broader audience with some detail of the plan being executed. The War College was a convenient, friendly venue.
If it is your intent to send this article for publication, it seems to me you are making a much greater mistake than that for which you fault the President. Professions of loyalty and support, as you have evidenced in the past, would dictate, in my opinion, that corrections/criticisms be issued in private rather than in the public press.
I would guess you do not have many opportunities to voice your thoughts to the President in person, but, since the subject matter doesn't appear to be something that will lose the war, or lose the election, perhaps it can wait until you do have that opportunity.
I think it was good of you to post your thoughts here before going public. I trust you'll meditate a bit on what might occur as unintended consequences.
