"This war against the LTTE started in August 2006. The LTTE blocked an irrigation canal in the Eastern provinces which were controlled by the Tigers. The government objected to it. They said this is a cruel thing to do because hundreds of farmers's livelihoods were dependent on it. The LTTE claimed they created an obstacle in the canal project only because the government had not delivered on some other plans and broken promises to release money for development projects for Sri Lankan Tamils. The tussle over the canal was the first flashpoint that has now ended in the decimation of the LTTE.
The government chalked out a plan to get aggressive. In just a few days, on August 10, 2006, the government closed highway A-9 that connected Jaffna to Colombo. In one stroke that decision affected some 600,000 Sri Lankans who were completely got cut off from the rest of the world.
A-9 is not an ordinary highway. It was a cash-cow for the LTTE. Every item that entered north of Killinochi from the south and mid Sri Lanka was taxed by the LTTE.
The money collected on A-9 was the main source of finance for the LTTE. Their military was strengthened from the tax collected from A-9. The government erected their own entry and exit points on A-9. It was a huge blow to the Tigers.
The LTTE understood the game. On August 14, 2006, two very important events took place. Pakistan High Commissioner retired Colonel Bashir Wali was unsuccessfully attacked.
The same day the government conducted an aerial raid on a school in Mullaitheevu district; 53 girls were killed. The government defended the action, saying the school was training 'suicide bombers'.
In December 2006, a suspected LTTE suicide bomber rammed an autorickshaw into a convoy with Sri Lanka Defence Secretary Gothabaya Rajapakse, the president's brother. He had retired from the Sri Lanka military two decades ago and ran a store in the US. A green card holder, Gothabaya returned to the island at the government's invitation to take over the defence establishment.
