We are all apologising for lateness, but I was not as late as the others.
As we learned from Northern Ireland, individual issues can build up to create a sense of grievance. That is the case with regard to the proscription and non-recognition of the LTTE. Although there can be informal dialogue, nothing can substitute for more formal dialogue and recognition. Removing the ban would undermine one of the elements of the sense of grievance that contributes towards the conflict.
