President Obama made the case for striking ISIS during an address at the UN: “No God condones this terror. No grievance justifies these actions. There can be no reasoning — no negotiation — with this brand of evil. The only language understood by killers like this is the language of force. So the United States of America will work with a broad coalition to dismantle this network of death.”

+ WaPo’s David Ignatius: The administration has “focused on five main lines of operation against the Islamic State: direct military action, counterterrorism operations against foreign fighters, disruption of financing, humanitarian assistance, and media activities to ‘de¬≠legitimize’ the extremists.”

+ The most memorable address at the UN this week may have been a young mother’s poem about her vanishing country.
