The Barbarians are not at the gate. There is no need for a rush to war as the French president, Francois Hollande, suggests. The Americans did this after 9/11 and raced into Afghanistan with the intention of eliminating al Qaeda. They failed and they are still in Afghanistan, the US’ longest war ever. They have become bogged down in fighting Afghan movements, including the Taliban. Some of the Taliban may have hosted al Qaeda for a while but accounts suggest they were not happy about it. They certainly do not today.In Harvard University’s magazine, International Security, Professors Alexander Downs and Jonathan Monten report they have studied over 1,000 military interventions over many years. It is very rare that there has been success. Bogged down, bogged down. These two words should resonate in every western (and Russian) leader’s head. Vietnam, Iraq, Afghanistan, Lebanon and Libya (also Russia in Afghanistan and in Chechnya). There is such a long list of failures. Give one good reason why it should be different this time.Think of the innocents: 200,000 civilians died in Iraq because of a war that the US and UK started. In Paris, in comparison, 130 have died. Already many more innocents than that have been killed in Syria/Iraq by US, French, Russian and Gulf states’ warplanes. And there will be tens of thousands more if the bombardment is continued. Mea culpa. Let us be careful about conflating the issue of Assad’s civil war with the issue of Islamic State (IS). What triggered Syria’s civil war had nothing to do with what triggered IS. The two began for very different reasons. IS is al Qaeda, metastatsising into a more virulent form. Its main raison d’être is not to defeat the Shia-supported Assad, although that would be welcome. It is to drive the western infidel and his ‘stooges’ in Muslim countries out of the Middle East and create its own ‘pure’ Islamic caliphate. It is to revenge itself upon the west for centuries of its ‘terrorism’- the crusades, the post World War I seizure of territory, the one-sided exploitation of oil, the creation of Israel on Islamic soil and the subsequent Israeli take-over of much of the Palestinians’ land.The backbone of IS comes mainly from Iraq. They are ex-Baathist soldiers who supported Saddam Hussein and who feel that the US-imposed Shia government in Iraq has discounted them. Say it loud: President George W Bush and British Prime Minister Tony Blair unleashed the demons that have made IS the formidable enemy of the west and Russia (and soon perhaps China) that it is today.Is there an alternative way of defeating or at least containing IS? There are other ways apart from war to cut IS down to size: sanctions that make sure funding is cut off and its leaders and supporters cannot travel, use banks or money transfer businesses. Private donors to IS in Saudi Arabia and Qatar must be arrested. Cancel the passports of those jihadists resident in the west and Russia who have gone off to fight. Take away the European and US citizenships of those who present a terrorism risk and have dual citizenship. They will have to pay the price of never seeing their families again. Enhance the defensive deployment of Iraqi troops to protect the revenue-giving oil wells.At the same time the west needs to continue with its so far successful efforts to stymie terrorist activity back home. However, it must not work itself up and exaggerate its vulnerability. Until Paris there had not been a major terrorist outrage in the west since 9/11, the bus bombing in London in 2005 and the train bombing in Madrid in 2006. Encircle IS and squeeze. Encourage the towns they occupy (Raqqa for instance, which France is now bombing) to empty out and their native inhabitants to head for refuge in Turkey, Jordan or Iran. Then deny the IS militants — once they move into a town — food, water, phones, electricity and medical supplies.Something not too dissimilar was carried out by the Russians in their war against Napoleon. Muscovites were ordered to abandon the city. From that moment on, lacking fresh supplies and shelter, Napoleon’s campaign went downhill. The refugee camps must be made more enticing. At present, they are cutting their budgets because of the lack of funding from UN members. Funds for food, clinics and schools in the camps have, over the last year, been seriously cut back. If people are to leave behind their towns, work, schools and health services they need good facilities in the refugee camps. Within a couple of months these new refugees should be able to go home. If the IS invaders have no water, food, phones, medical supplies and electricity they will not last long.This is what is called lateral thinking or thinking outside the box.
