Tiny blips on radar often end up causing the most damage.Though,there is virtually nothing the Tigers can gain by attacking India(unless Delhi decides to intervene again),the Southern tip/coastline of India is virtually unprotected by active airforce & naval assets-it’s mostly the Indian coastguard which is active & is more or less very vulnerable.
All that being said,the Tigers at the end of the day are a political problem which can only be solved politically.They will lose their support among the Tamil populace if the Sinhalese elite start treating the ethnic Tamils as equals as it was nearly 30 years ago.
They sure look like a pain in the wazoo
SL is a problem, no doubt
