In late May of this year Sri Lanka's Government declared victory over the Tamil Tigers ending a 26 year long civil war. Engagements in this conflict ranged from classic hit-and-run insurgency to pitched stand-and-fight battles. One of the most sophisticated rebel movements in the world the Tamil Tigers had an army, navy, and fledgling air force. They also pioneered/refined the widespread use of suicide bombers. According to the BBC the conflict started after ethnic Tamils felt discriminated against during successive Sinhalese governments. This leaves multiple scenarios which could play out in Sri Lanka to the population's benefit or woe.
Scenario One, "Best Case":
In this scenario the current government and successive government initiate massive reconstruction projects in the former Tiger's territory, and provides security. In addition the physical changes that reconstruction brings in this scenario the government increases education, economic opportunities and most importantly representation in successive governments. In the long run if any escaped Tamil Tigers make it back to Sri Lanka they will find a public unwilling to take up arms again, because all the grievances that existed previously have been removed.
This scenario is not just a "best case" but seems to be the direction in which the government is going. USAID is running a program to help rehabilitate former combatants, while the Chinese government has provided equipment at concession prices to the tune of ~$17 Billion. In addition the government has acquired five additional for a total of 19 de-mining machines to speed up the removal of unexploded ordinance/mines. While this last fact might seem small, the worldwide economic costs of loss of farmland and medical costs to people disabled by unexploded ordinance or mines, is huge. According to the UN:
"From another standpoint, landmines often stop the economy of a nation. Most minefields are unmarked and cannot be distinguished from the surrounding countryside. Generally, the first sign the people in an area have of the existence of a minefiled is when a friend or family member is injured or killed. Since this is such a serious matter, local civilians are forced to avoid any area in which a person is known to have died due to a landmine. This means that the explosion of even one mine may make a road, playground or a rice paddy unusable. In areas where there is a shortage of food, people are sometimes forced to take the risk and work the fields that might be mined."
Emphasis must be placed on the youth and young adult groups because they are the potential combatants for the next conflict. This rehabilitation movement is one that will last multiple generations and will be costly, but will remove the chance of Tamil Tiger resurgence. Also the economic incentives should result in higher incomes for Tamils which will ultimately increase revenues to the state through taxes.
Scenario Two "Most Dangerous"
This scenario is essentially a do nothing scenario. Having been successful militarily the government demines the north while not actually changing the socio-political landscape. Representation of Tamil minorities remains low and the north and east remains impoverished and ripe for Tiger resurgence. While at this stage in the game this scenario seems unlikely a change in government could easily roll back all the progress that has been done. Many Sri Lankans will look at the expenditure of the government on the north and east and may feel resentful that the perceived wealth is not being spread on their communities. These citizens would forget what the costs of the 20 year conflict were.
The government must remember that the logistics and financial network of the Tigers still exists and is waiting for new leadership cadres, which will be formed from today's youth and young adults. The prejudices of the parents will be passed on the children and tensions will rise to the tinderbox level where one miscalculation will result in widespread unrest and subsequent repression.
Scenario Three "The Middle Ground"
In this case either the present government loses interest in reconstruction, education, economic opportunities, etc., or a successive government rolls back many of the initiatives started by the present one. While the region might be restive in the short-run a lack of change would make the population receptive to separatist sentiment. The Tigers would be reborn in later generations and the conflict would be renewed at great cost to all Sri Lankans.
