The CPI on Sunday said the US cannot apply pressure tactics on India for pushing through the nuclear deal.
Reacting to US Ambassador to India David Mulford's remarks in an interview, CPI MP D Raja said India was a sovereign nation having a vibrant Parliament and cannot be hustled into taking any decision under pressure.
He said the US Ambassador's remarks that if the deal was not processed in the present Congress it would not be offered to India again amounted to "intimidation".
Raja said India was developing its own nuclear technology and looking for alternative sources like uranium and thorium.
He said the US was looking at business in India through the deal and India should not succumb to its "blackmail".
