The Western powers began to seriously examine the question of terrorism in the wake of the Oklahoma bomb blast in 1995. Initially, Islamic fanatics were suspected of being behind the terrorist attack. That was a time that everybody thought that those capable of that kind of terrorism could only be Muslim fanatics. But to everybody's surprise, the terrorists turned out to be white, Christian Americans. That made everybody stand up ant take notice.
Terror can come in many guises and without reason.
The reasons that are proferred are only a weak excuse for a pathological tendency. Moreover, not banning the LTTE after anti-terrorist legislation has been introduced will be a case of actively encouraging the LTTE in its campaign of terror. In the past Britain had the excuse that they did not have the laws necessary to ban international terrorist organisations from operating from Britain. But now the legislation is in place and if they do not apply it to the LTTE, which has already been banned by many countries including the USA and India, then that will constitute an act of deliberate encouragement - an acknowledgement that the LTTE is justified in its actions. It will also be a tacit go ahead to the LTTE to step up their operations while the British turn a Nelsonian eye to their activities.
