By Francis Harris in Washington (Filed: 29/08/2006) Britain now presents a greater security threat to the United States than Iran or Iraq, an American magazine said yesterday. In an article on Islamists headlined "Kashmir on the Thames", the New Republic painted Britain's Muslim communities as a breeding ground for violent extremism. Citing recent opinion poll evidence suggesting that one in four British Muslims believed that last year's London Tube bombings were justified, the magazine said: "In the wake of this month's high-profile arrests, it can now be argued that the biggest threat to US security emanates not from Iran or Iraq or Afghanistan, but rather from Great Britain, our closest ally." advertisementThe magazine, with a circulation of 60,000-a-week, has its roots on the Democratic Left although in recent years it has backed much of President George W Bush's foreign policy. The claim is the latest in a series of hostile reassessment of Britain by Americans in the wake of the alleged plot to bring down transatlantic airliners. Many have been appalled both by the existence of enthusiastic jihadis in British cities and by the call from some of their leaders for a change in the country's foreign policy. Other publications and the think-tanks that shape public debate in America have also issued stern criticism both of Britain's Muslims and of the Government. Nile Gardiner, of the Right-wing Heritage Foundation, told The Daily Telegraph yesterday that Americans were coming to view Britain as "a hornet's nest of Islamic extremists" and thought it posed ''a direct security threat to the US". He said that if British-based terrorism continues, America is likely to respond harshly. http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/08/29/wsecurity29.xml This is where America is headed. Jihadists are not a minority, but the majority.
