IRAN

President Obama took on critics of the Iran deal in a speech at American University. Obama suggested that the people opposing the deal are the same ones who created the “drumbeat of war” and exploited the public’s fears, pushing the US into the Iraq war. The president went on by saying:

So let’s not mince words.  The choice we face is ultimately between diplomacy or some form of war — maybe not tomorrow, maybe not three months from now, but soon.

…how can we in good conscience justify war before we’ve tested a diplomatic agreement that achieves our objectives; that has been agreed to by Iran; that is supported by the rest of the world; and that preserves our options if the deal falls short?

Further discussion is provided by Julie Hirschfeld Davis at the New York Times and Dan Roberts et al at the Guardian.

The Pentagon’s recent shift in how it describes the threat posed by Russia is “not sitting well” with the White House, where Moscow is considered one of a “myriad threats,” rather than the “existential” danger claimed by military officials, write Nancy A.

 … the Obama administration’s plan to help the country rebuild its military, joined by other NATO governments, […] came to symbolize the shortcomings of the West’s approach to post-revolution Libya. Undermined by insecurity and political divisions there, the flagship assistance program revealed not only the hollowness of Libyan institutions but also how different parts of the US government worked at cross-purposes, dooming a project that Obama ­selected as a personal priority.
