First thing pakistan has to do is to draw the line between terrorists and pakistanThen how do you want terrorist acts to end and Pakistan to act on it?
It takes time, something which India does not want to give Pakistan.
It's still unclear from the Indian side what they want, and it's not only the attitude of the GoP, it most definitely is the attitude of the GoI, it's not doing the process any good with these election stunts.
Actually pakistan was successful in it for brief time..Then again for some domestic consumption they showed the other part..
Now tell me what will pakistan do if some people from some country come and attack on general mass like what they did on mumbai streets..
It is difficult to believe here that state elements are not involved in it(attitude of pak govt adding fodder to it)Here pak govt can do much more..
If once Indian mass were confirmed about good intention of pak govt(if there is) then pressure on both govt will be diffused...and tragedies like these have the potential of begining a war as well as long lasting freindship..
conclusion:pak govt has to come clean out of this incident so that there will be place for any good relation
