Sir: Finally it is encouraging news that the USA along with China has urged Pakistan and India to solve differences over the issue of Kashmir. Kashmir is the main bone of contention between the two countries. It is believed that Kashmir is the root cause of other problems. Being an ally in global war on terror to the West and especially to the USA, Pakistan must be supported by these countries and the USA must come forward and play its role in the resolution of tension between India and Pakistan. Undoubtedly the USA has immense influence over both disputing nations. If it becomes a mediator then this muddy situation can be avoided. This act will increase the trust between the people of Pakistan and the USA, especially those who blame the USA for everything. Above all it is the moral responsibility of the USA to play its role in settlement of issues that may lead to war. Both countries are nuclear powers. Any miscalculation and delay in peace talk could prove fatal to not only regional nations but also to global peace. AFTAB AHMED JUNEJO Hyderabad
