US is a wrong analogy here. It is no one's case that we invade Pakistan.
However, is it not shameful that after every blast, most of government energy is not spent on finding the culprits or root causes but assuring (whom ?) that peace process will not be derailed!
Be firm, stop these silly games of people to people contacts, stop trade, revoke MFN status, declare Pakistan as terrorist country (Do not look to US for it, do it yourself), scrutinize movement of funding.
You will definitely get votes too and you may not lose the category of votes you are afraid of.
