If Indian PM boycotts the CHOGM, it is likely to add to Sri Lanka's bitterness. This would not help India's desire to add more depth and content to its relations with Sri Lanka but its ability to influence Sri Lanka's decision making process on the both strategic issues and on Tamil minority issues, says Colonel (retd) R Hariharan.
If the two Dravidian parties up the rhetoric it increases the risk of Tamil Nadu becoming a safe haven for Tamil extremism with serious implications for national security. As these developments affect Sri Lanka's internal security, it would kindle legitimate concerns in Colombo, says Colonel (retd) R Hariharan.
