I dont know about any party ........ But I think that ...... India needs many nuclear test to be sure of security if any threat come from china or Pakistan ............. coz what evr we tested is of 43KT which look like cracker in front of China 's weapon 4-5 MT around 100 times more powerful ......... you cannot deny the fact that all the time US want to curb India'S Nuclear Programme of weaponisation ....... thats y they formed NSG .........if you see they are not signer of CTBT but always force India to sign it ....... They already decieved us in case of Tarapur reactor ............... They also want to curb Indian FBR programme which can create weapon grade plutonium on large scale indirectly it will effect Thorium technology which are underdeveloopment in FBR at kalpakkam ......... So just for energy security you cannot compromise ... Security against threar and make wholee country energy dependent on others
