We are not signing any deal with Howard. The agreement is with Aus, not the party who rule Aus. So is case with India. For domestic political reasons, like BJPs case in India, they will do such things. But it is only untill they get power (if they). For instance BJP themselves showed it in the past. They were fierce oponents of the economic reforms while in opposition, always demanding swadeshi. But after getting powwer knowbody really knows what happened to their swadeshi.
The foreign policy is there to continue. Also we are living in a new world. To behave irresponsibly, either they should be North Korea or Pakistan.
