Recall that our foreign aid deal with Egypt sprang out of the fact that Israel and Egypt have been involved in two outright wars. The deal is not without a rationale, but it’s been used for too long to prop up a corrupt and double-dealing regime in Egypt, almost as a bribe to stop them from becoming aggressive again.

There are realpolitik reasons behind all of this, but a photo of a tear gas can made in the USA is a powerful image.
