In the post-Mumbai carnage, India's highly provocative actions such as mobilisation of troops and tightening security at airports and violation of Pakistan's air space have created an alarming situation in the region as Islamabad has also taken defensive steps in response to meet any prospective aggression. On December 26, 2008, after receiving reports that Indian surgical strikes cannot be ruled out, Islamabad started moving thousands of military troops from the Afghan border and the tribal areas to its border with India. Meanwhile, setting aside Pakistan's offer for joint investigation in relation to Mumbai devastation, Mukherjee who had earlier warned Pakistan against diverting its attention from fighting terrorism, calling on its leaders to "bring to book the perpetrators of the Mumbai terrorist attack," has softened his illogical stand to some extent. As regards the efforts for diffusion in escalation, Mukherjee while meeting Saudi Foreign Minister Al-Faisal and talking to foreign ministers of various countries conveyed India's dissatisfaction over Pakistan's actions against those responsible for the Mumbai tragedy, asking them to pressurise Islamabad in this regard. On the other side, Pakistan's civil and military leadership has repeatedly made it clear that our country would retaliate with full force if attacked by India. Particularly, General Kayani recently said that the Pak Army was prepared to deal with any aggression. So far as the Indian blame game in connection with the Mumbai attack is concerned, it is surprising to note that neither New Delhi nor UN Security Council has presented any solid evidence regarding the alleged involvement of the banned Lashkar-i-Taiba and Jamaat-ud-Dawa against whom Pakistan has already taken action in accordance with the resolution 1267. In this respect, Foreign Minister Qureshi reiterated on December 17 that India should share evidence of involvement of Pakistan-based groups in Mumbai tragedy through "diplomatic channels and not through media." Congress-led regime of India, which is under pressure of a hysterical media - acting upon the hot pursuit policy of the Hindu fundamentalist parties like BJP, RSS and Shiv Sena including military hawkish elements wants to make Pakistan, a scapegoat of the Mumbai carnage to win the coming election. It must know that Pakistan's deterrence is credible, making its defence invincible. Without any doubt, Pakistan possesses a variety of nuclear weapons and missiles which could be used against India as the last option in case of war. While both the neighbouring adversaries are nuclear powers, Indians should not ignore the principles of deterrence, popularly known as balance of terror. In 1945, America dropped atomic bombs on Hiroshima and Nagasaki as Tokyo had no such devices to retaliate. After the World War II, nuclear weapons were never used. These were only employed as a strategic threat. During the heightened days of the Cold War, many crises arose in Suez Canal, Korea, Cuba and Vietnam when the US and the former Soviet Union were willing to use atomic weapons, but they stopped due to the fear of nuclear war which could culminate in the elimination of both the superpowers. It was due to the concept of 'mutually assured destruction' that the two rivals preferred to resolve their differences through diplomacy. In the present circumstances, India is badly mistaken if it overestimates its own power and underestimates Pakistan's power. While taking lesson from the recent history, the best way for New Delhi is that instead of raising war hysteria, the present issue of Mumbai terror attack could be resolved through joint investigation which Islamabad has repeatedly offered. And India must better pay attention to her homegrown Hindu terrorists by abandoning irrational allegations. Otherwise, any misadventure against Pakistan could definitely lead to national suicide of the two nuclear rivals. The writer is a foreign affairs analyst Email: sajad_logic@yahoo.com
