I think the LTTE has been very powerful in organizing, providing leadership, and indeed putting political pressure on the Tamil diaspora around the world, and certainly in Canada, especially in Toronto.
I think the difficulty is that there has been no other political force around which Tamils could rally to try to achieve reforms or justice for the Tamil minority in Sri Lanka. That's partly due to the LTTE murdering their opponents and competitors. It was historically a very brutal movement. They have been very effective internationally in generating support, in pressuring people to provide support where they might not have done it spontaneously, in raising money for their movement.
You saw in the rally in Toronto the number of Tiger flags. There's a lot of sentiment in the rest of the world to that effect. One of the reasons for that is there has been no other alternative political formation around which Tamils seeking reforms could rally.
