A seder is a long thing, and so the choice of this single image, of all the images that must have been created last night at the White House, is quite deliberate.

Here we see the president tapping out one drop of red wine for each of the ten plagues visited upon the ancient Egyptians (as the story goes) by the vengeful God of the Jews. Blood, frogs, lice, wild animals, pestilence, boils, hail, locusts, darkness, and, finally, the killing of the first born.

As the story goes, this God of the Jews was upset that they'd been enslaved by the Egyptians and, after some other efforts, this God of the Jews decided force was the only way to free them from bondage. Today, the tradition of tapping out one drop of wine for each of the plagues cast upon the Egyptians is meant to symbolize a sympathy for a people who, as the story goes, had to be hurt in order to free another people.

In the photo, we see in action the same finger that, with the push of a button, can visit darkness, blood, and worse upon any place or people on earth. Its owner looks like he would if he had to. He also looks like he would not like it.
