When the 123 agreement was just signed and the P.M. took the BJP into confidence and discussed the details of the deal they seem content. In fact we did read in some of the newspapers that BJP took credit for the deal saying that it was because of their pressure that we got the deal what we got from the US!
However the second the Chinese tail started wagging in anger the BJP changed their tune and looking at an opportunity to embarrass if not to bring down the government they are now singing a different tune.
