Citing the collapse of the Berlin Wall that unified Germany, Finance Minister Pranab Mukherjee said differences between India and Pakistan may be resolved one day since the two cannot wish each other away and live in perpetual tension. Speaking at the launch of eminent journalist M J Akbar’s book ‘Tinderbox–The Past and Future of Pakistan’ in New Delhi on Tuesday night, he however added that how the course of history will take turn, nobody can predict with precision. He said the collapse of the Berlin Wall and formation of the European Union were not foreseen but took place. The senior Congress leader said one can be selective in choosing friends but not neighbours. Describing Pakistan as India’s most important neighbour, Mr Mukherji said, the stability and well-being of Pakistan is in the interest of this country as the two could not develop and prosper in isolation today.
