Brother, Tigers are not fools in war. If Rajapakshe goes another man/woman will come to that post.
1. Destabilise Srilanka socially and financially and internationally. This is called First goal.
2. Destabilise srilankan military. This is called final goal. Next day sinhalese are at LTTE's feet.
Tigers are doing the first point now. And because of that Rajapakshe has to go and fall at the feet of POPE in VATICAN. All the international human rights organisation are riding Srilanka and Rajapakshe now.
Once the first point is finished. At no time LTTE can finish off Srilanka's military.
But at present even if LTTE can do, they cant target Srilankan military and finish off them. Achieving the First point (first goal) is GATE WAY and SIGNIFICANT for the new country "ELLAM".
