Approved for public release, distribution is unlimited / Ethnicity, sectarianism and economic instability are fundamental variables of internal security threats to Pakistan. Religious extremism has created an unenviable image of Pakistan in the eyes of the rest of the world and has affected the country adversely. At the same time inter-provincial grievances could potentially cause serious damage to the federation. Despite recent economic recovery and sound macro policies, the absence of genuine socio-economic development has provided ethno-sectarian elements and regional forces grounds to exploit and weaken Pakistan internally. This paper argues that ethno-sectarian problems are major security threats to Pakistan and will remain a huge impediment to the goals of economic prosperity. Interdependence of these multifaceted threats and their overall impact on internal security is the focus of this analysis. Pakistan needs to address these national security threats and find a viable solution in a reasonable timeframe to find its rightful place in the community of modern nations. The immediate requirement is to introduce political, economic and education reforms and take bold initiatives to obviate present and future threats. This paper recommends three-pronged strategy to counter ethnosectarian threats to Pakistan: halt then reverse present trends, enforce rule of law and lastly introduce fresh incentives for socio-economic development. / Lieutenant Colonel, Pakistan Army
