I personally think Cameron is a idiot (he is not gonna last long in power), but I agree with my prime minister - Pakistan needs to stop exporting terror.
Although one can understand Pakistan's actions, fight the terrorists hurting their country, however keep it cushy with the good terrorists who will come in handy in times of war against India.
Anyways, I believe Cameron's words are empty, I doubt he is going to actually do anything, he just said it to please the Indians because the UK needs investment, due to our economic crisis. It will be interesting what happens when Zardari arrives in UK!
