You want to believe what you want and have not real understanding of what is happening. Don't you think US folks from opposition party(Berman is a democrat whereas Bush is Republican) would like to delay this deal?
Also, this opposition by some US politicians is clearly proving that whatever MMS had said was correct. There is no tie-up mentioned between NSG waiver and US law!
Here is something more Berman had to say: " Meanwhile other countries might rush in to take advantage of a more lenient NSG waiver and do business with India on their own terms," Berman warned.
"This would give other countries an unacceptable head-start in securing commercial nuclear contracts with the Indian Government, thus placing U.S. firms at a competitive disadvantage," Berman wrote to Rice.
