The US is entitled to its own opinions and interpretations, so are we. But facts are facts and must be stated. Right from the beginning of this unfortunate situation that has arisen in the subcontinent, India had been asking for a political settlement acceptable to elected and acknowledged representatives of the people of Bangladesh."
