This was, of course, in reaction to yesterday’s developments that indicate sufficient Democratic support for President Obama’s Iran nuclear deal.

Ifill defends her tweet: of course she does. She has been a brazen cheerleader for the President since he was campaigning in 2008, and made it very clear that she sees nothing wrong with that, even when she was the moderator for the 2008 Vice-Presidential debate while her book about the inspiring achievement of Obama’s ascent to the Presidency—he hadn’t been elected yet, remember—was awaiting publication. PBS proved its bias (as if further proof were necessary) by shrugging off a blindingly clear conflict of interest and appearance of impropriety on her part then, and it will doubtlessly do so now. Ifill is defiantly pro-Obama. The tweet, however, is worse than that.

An American journalist taunting  the leader of an important American ally is unprofessional and, in this case especially despicable. Isreal’s legitimate concern about the Iran agreement is that under the best of circumstances, the scenario that the advocates for the deal admit, Iran will gain the resources to vastly enhance its support of terror in the Middle East, much of which will be focused on harming citizens of the nation that Iran has openly vowed to destroy. Take that, Bibi! Jews are going to die! Nyaa nyaa! Under the worst case scenario, the treaty makes it easier for Iran to wipe Israel off the face of the earth. How dare a nation’s leader express concern about his nation’s security and survival? Yeah, let’s make fun of him as the U.S. all but ensures a nuclear Iran 15 years from now.

Curt Schilling has been suspended by ESPN for making a legitimate historical observation that didn’t affect or relate to his job as a baseball analyst at all. Ifill’s tweet insults a world leader, displays gross partisanship, undermines PBS’s official pose as an objective news source and shows not merely terrible judgment, but the arrogance and shamelessness  that those who view themselves as immune from consequences eventually embrace.
