Left has always lacked in intelligence. As for their patriotism, it lies with China. They want India to be a junior partner of China. For the left the terms 'foreign policy independence' and 'sovereignity' are synonymous with 'aligning with China' and 'furthering chinese interests'. The US has gone out of its way to push India out of Nuclear Apartheid. There are limits to which they can stretch their laws. Already many US senators are feeling they have given away too much to India within the limits of non-proliferation. It is generally understood that Hyde act is a must but it will not be binding on India. Besides the age of Nuclear testing is passe. US and Russia have even tested conventional bombs that are more powerful than nuclear devices.
