Dear Sir, I strongly support the article and the author ; At the moment the ball is between the U.S. president and their congress : if their congress does not ratify the bill as it is and discussed by the two heads of their states, then only our P.M. can tell america that due to pressure from my parliament I cannot agree to the amended deal or not. At present it is just a storm in a tea-cup and a bit early to brouhaha about. Also we do need their help other wise what was the need to sign the agreement for and also it is fair and logic about them to worry about the Iran factor from their side and perspective.
