First sucker came when Sri Lankan authority removed the contentious article and offered unconditional apology. This should have created a question that if SL authorities intentionally posted such article? Why there was such a hurry in removing the article and offering unqualified apology? Point is simple. Such posts that encourage enmity between India and SL were posted not by Lankan authority!
Some informations also indicate that it was the handy work of Pakistani intelligence agency ISI, that wants to ruin friendly relations between India and Sri Lanka!
Narendra Modi is in the process to win the hearts of neighboring countries of which Sri Lanka is a very important part. Indian province Tamil Nadu sees Sri Lanka as an enemy country for historical reasons although the India and TN issue can be considered as an internal matter. The provincial rivalry particularly due to LTTE is beyond comprehension but Sri Lanka can't afford to insult neither TN nor India.
The hurry in which Sri Lanka tried to rectify the controversy with offer of unconditional apology proves that Sri Lanka was never involved in provoking India. Technically India's bete noir and allies of China were worried after Modi's campaign of winning neighbors! TN government must take note of the speed of Sri Lankan government in removing the controversial post and offer of apology. Had Sri Lankan government had any involvement; they wouldn't have corrected the mistake so swiftly.
There would be problem makers against Narendra Modi's vision of 'Sabka Saath and Sabka Vikas!' China was really frightened. That's why it gave a boost to Pakistan nuclear energy without considering the nuclear waste. Experts say that such nuclear boost to Pakistan would finally help landing the N-curse at the hands of terrorist units.
Point is simple, some say nuclear weapons act as deterrent. This is grossly wrong. Once a Pakistani outfit uses a low yielding nuke arsenal against India, India has to follow its nuke doctrine and Pakistan would be history in mankind of the globe! However because of such action not only India but the mankind of World would be at risk.
Indian government is trying hard to win neighbors. There are no doubts that there were historical reasons for enmity between TN and Sri Lanka. But when greater interest is required, selfish narrow interest should be sacrificed. Sri Lanka in fact is in a condition where it needs desperate support of India. If we try to take advantage of their weakness no doubt enemies would take leverage.
PM Narendra Modi and Tamil Nadu's CM Jayalalitha are the real statesman. Hope both will understand the context and Indian interest. Let the enemies of India get a combined blow from secular and democratic India!
