“Procrastination has been Obama’s worst characteristic in this crisis.” Natalie Nougayrède criticizes the administration’s approach to the Syrian conflict and the humanitarian crisis it has caused, opining that “[i]n the case of Syria, a whole body of international norms meant to counter state-sponsored massacres of civilians has been put aside,” at the Guardian.

IRAN

President Obama has stood by his comments comparing Republican naysayers to Iran’s hard-liners, saying that they’re “making common cause” rather than being “equivalent,” during an interview with Jake Horowitz, editor-in-chief of Mic.

The Obama administration ought to reengage Tehran in negotiations and get a “better” nuclear deal, according to Sen Chuck Schumer, who announced his opposition to the Iran deal last Thursday.

AFGHANISTAN

President Ashraf Ghani placed the blame on Pakistan for failing to crack down on the Taliban acting within its territory, after responsibility for a car bomb close to Kabul airport which killed at least five people yesterday was claimed by the group. Discussing recently improved relations, Ghani said: “We hoped for peace, but war is declared against us from Pakistani territory.” [Reuters; New York Times’ Mujib Mashal]
