While in Government, BJP supported go ahead clearance in principal for Sethusamundram project, of course DMK was a part of NDA then.
Now they are opposing the project and making a hue cry for RAM to gain political advantage.
Similarly, 123 Agreement with US, as such this was initiated by Shri ABV our then PM supported by entire NDA. Of course BJP was at the centre then. Now Congress carried forward what initiated by them. Now BJP make a hue and cry in the parliament opposing the agreement. Is it not dual policy ? Thus cannot be digested at this juncture. They have the only issue Hindus and Muslims / Christians. Come out from the sheel and do something for the betterment of the hapless indian public. Do not oppose good things for the sake of opposition.
