"...[W]e should resist the temptation to react to the fear of terrorism by turning inwards, reducing ties to foreign countries, and denying more students entry. Reducing the number of foreign student Visas would be counterproductive. The US tried it after September 11th, but has now reversed its approach, realising the harm it is doing. To do the same would be to be cowed into becoming a more closed society. We must remain open, outward-looking and vibrant. It is precisely many of these foreign students who will help their countries to reduce terrorism over the long run."
