If you carefully observe tamilnadu politics, LTTE is often found only in the mouth of the politicians. Open support to militant tamil groups were extended by centre and major political parties like ADMK and DMK , till Rajiv's death. After that , the Centre, ADMK and DMK did not support militant groups openly and directly. Minor political players like MDMK, PMK, VC etc support militant groups openly , but their support is also only orally and they donot show any thing really in action. And these minor political parties are allies of DMK and ADMK , thereby it is also balanced. A section of the people in coastline directly help the militant groups , not for any ideology etc, but only as business. They are paid huge sums in return fo diesel, medicines etc.
Poor srilankan tamil civilians are the real sufferer as they are sandwitched between the tamil militants and the srilankan army.
