ISLAMABAD (Agencies) - Pakistan cannot afford to match the induction of modern weaponry by India, which possibly has a greater capacity to sustain a war, Defence Minister Chaudhry Ahmad Mukhtar has said. If we only try to match them (India) militarily and buy the sort of armament which they have, we will probably not be able to afford it, Mukhtar said. Explaining his contention, he noted that Indias economy is six to seven times bigger than Pakistans and its trade volumes were five to six times greater. The capacity of India and Pakistan to fight was for 20 to 22 days. Now India has inducted a lot of armaments, may be they can last for 45 days, we will not be able to do so, Mukhtar said in an interview to BBC. He was responding to a question on whether the projection of India as Pakistans greatest enemy was the root of the countrys problems. Mukhtar noted that the two countries were taking steps to improve relations in the aftermath of the 2008 Mumbai terror attacks. Slowly the process of meetings has started. People are going across the border. Nobody had ever thought they could walk suitcase in hand to Amritsar via Wagah but that is the reality now and it is happening, he said. This was happening, he said, in spite of the fact that wars were fought, there were problems on the border and the Mumbai incident. Asked why an incident like the Mumbai attacks occurred whenever relations improved between the two countries, Mukhtar said: It is very unfortunate that such incidents happen and they should not happen. But there are players who are behind these incidents. He did not give details about such elements but said some of them had been arrested and put on trial. Matters would improve when we decide that religion and politics should not be mixed together, he said. Let them go side by side. There should be no restrictions on religion which is between me and my God. In the wide-ranging interview, Mukhtar said Pakistani military wants a speedy probe into the failure to detect Osama bin Ladens presence in the country as well as the US raid that killed the al Qaeda leader in Abbottabad on May 2. The military wants the work to be completed quickly so that responsibility can be fixed and they can be punished... A security lapse is something for which a person can be punished. I do not believe there was a security lapse in the Abbottabad case, he said.
