Sri Lanka.
Streets were filled with joyous scenes of jubilation. United National Party leader Ranil Wickremasinghe, through a telephone call, congratulated President Mahinda Rajapaksa and the state's security forces on 18 May 2009 for their victory over the LTTE. In a press release issued that day, Roman Catholic Archbishop Oswald Gomis said:
 ;templatestyles src="Template:Blockquote/styles.css" / ;I congratulate His Excellency President Mahinda Rajapakse, President of the Democratic Socialist Republic of Sri Lanka, for his very courageous leadership and thank the Chiefs of the Defense outfit who supported him with deep commitment and self-sacrifice. I also offer my deepest sympathies to those who laid down their lives in battle and those innocent civilians killed, trapped in war.
In a sense we could say that we have won the battle but the war is not ended. The war would end only on the day that we grow in nationhood realizing that we are all one people in one country with equal right. We have to realize the fact that we are a multi-ethnic, multi-religious and multi-cultural community. As such we are now left with the great task of nation- building forgetting our ethnic, political and religious differences.
It is imperative that there be a political formula that will inspire confidence and promote a sense of belonging among the minority groups in the country. We have to leave the sad and bitter memories of the past three decades and look positively and optimistically towards the future in hope. All of us have to share the blame for our division and forgive each other. We should have the humility and wisdom to learn from the sad experiences of that past.
It is then, and only then, that we could build nationhood that will bring true peace and prosperity to our beloved country – Sri Lanka. Let us always remember that united we will flourish but divided we will perish.
With the announced end of the war, Sri Lanka's stock exchange registered its sixth highest percentage gain ever.
