The UAE has turned into a terrorist recruiting hub for Indian RAW. Its agents (many times pretending as Muslims) keep finding those Pakistanis having financial or legal issues in the UAE, help them out, and then exploiting and turning them into target killers (or a link to target killers in Pakistan) for killing people in Pakistan.
While Pakistani government needs to seriously talk with the UAE government to discover, arrest, and punish those Indians of RAW terrorist network in the UAE, that might not be enough of a measure. The evil Indian mindset will not be deterred by such defensive response. Indians understand the language of violence and killings only.
Pakistan needs re-create similar networks in India. Fortunately, India offers very fertile grounds because of there is inbuilt oppression in Indian union resulting in deep and glaring cracks in terms of caste, religion, and ethnicity.
The current Indian home minister has officially admitted in Indian parliament of target killing more than a dozen Pakistani citizens in Pakistan through RAW's terrorist network. Dare devil Indians keep officially and openly admitting their use of terrorism in Pakistan without any hesitation. There is a justification for Pakistan to respond in self-defense.
Indians understand only the language of tit for tat. One very serious damage that dictator Musharraf caused to the state of Pakistan was abolishing Pakistani assets/networks in India. Until we start responding to Indian terrorism in Pakistan (including their open support to BLA and TTP terrorist organizations) in the same coin, Indians are unlikely to stop their terrorism against Pakistan.
