19 LTTE Killed

Here is some more current information on the LTTE. while fighting in the north there were 19 members of the LTTE killed and some others wounded. Through a series of small attacks and small fights in the north there were several members of this terrorist organization killed, there were also a couple of SLA soldiers killed in the attacks. My question is, when there are more casualties to the terrorist group than there is to the target is the attack really worth it...any opinions. I can't imagine how it would be beneficial to the terrorist group to attack and lose so many 'fighters' without at least an equal number of deaths on the opposing side.
