For the West's masters of war, it's a good time to be in Wales. A military alliance that has struggled for years to explain why it still exists, NATO has got a packed agenda for its September 4 and 5 Newport summit. NATO may not be at the centre of US President Barack Obama and British Prime Minister David Cameron's plans to ramp up intervention in the Middle East and wipe the so-called Islamic state “out of existence”. But after 13 years of bloody occupation of Afghanistan and a calamitous intervention in Libya, the Western alliance has got an enemy that at last seems to fit its bill.
