Analyzing the recent unconventional terrorist attacks on Pakistan military’s strategic assets, tactics employed, methods used, and skill shown by the terrorists’ points towards Indian involvement. Both in the case of Mehran and Kamra attacks the assets targeted had nothing to do with Pakistan's war on terror, rather both assets were India-centric and provided Pakistan defense forces an advantage which countered Indian military supremacy.
While many people are pointing to "insider" information theory, I think Indians are utilizing their newly acquired "eye in the sky" advantage to spy on possible target areas and giving the signal to already embedded terrorist teams in the vicinity living as civilians waiting for such signals.
GOP should not treat these incidents as random acts of terrorism should investigate this from a different angle. If Indian involvement is confirmed, Pakistan should also carry out such operations and destroy Indian strategic assets in a tit for tat move. Not responding to India in the same language would embolden them and future attacks on Pakistani assets might be bigger, more successful and disastrous.
