Meh? Really, meh?
First of all, come down out of your cloud, no President, even a "bad" one, "skips security briefings."
But the recent example of a "bad" President, i.e., one who is literally ignorant about the rest of the world and woefully unprepared to lead our nation, the Dub, is staring you in the face as a cautionary tale.
His Iraq war is the single worst foreign policy mistake in recent history, by a large margin. You can have all the experts you wish, but if you have an ignoramus at the center, a brutal and bloody and costly in every way possible tragedy like what Bush/Cheney perpetrated on us can and will occur.
I know what and where Aleppo is, and why knowing about it in the context of Syria is important. I assume you do, too. Most all of the posters here in this forum do, as well. Gary Johnson, laughably, did not.
If that doesn't scream to you what a shallow, unprepared, Clown College candidate to be our Commander-in-Chief he is, I don't know what else to say, except Gawd help us all.
