Its very funny how Indians see "terrorist launch pads" 500 meters inside Pakistani borders. To them, if they exists, they must be some billion dollar worth infrastructure which if destroyed Pakistan will not be able to rebuild for another 10 years. Otherwise why would they risk their lives to target something which they could have hit by staying within indian borders.
But mind it, however you do it - there must be no evidence even for your own benefit. It must be a mythical story which half of your countrymen doubt and other half could believe because they were too afraid to ask questions.
Go on buddies, have more of your soldiers killed. Pakistanis won't spare your stupids trying to cross LOC. Don't expect them to treat you with Ladu.
