Identify the causes and impacts of the Kurdish Genocide

Please give me a very thorough answer

Occasionally, opportunity can grow out of tragedy. For Middle East Watch, the opportunity to carry out human rights research in northern Iraq for the first time opened up unexpectedly, in the wake of the tumultuous, heart-wrenching events of early 1991 familiar to most readers from their television sets. As Iraqi government troops fell back in the face of advancing allied troops and Kurdish peshmerga fighters, returning along with civilian refugees from the Turkish and Iranian borders, it became evident that Baghdad's long-standing ban on access to the Kurdish region by independent investigators had been broken -- by force majeure. How long the window of opportunity would stay open no one could predict.

The debilitating uncertainty remains. For the Iraqi Kurds, their future as an often-threatened minority as well as their lives are at risk. As of this writing, a severe economic squeeze, resulting from a combination of UN sanctions against Iraq and an internal blockade imposed by government forces, threatens to produce mass starvation among the 3.5 million inhabitants of the Kurdish rebel-controlled enclave. Government troops massed along a ceasefire line could easily reconquer the region before the West had a chance to come to the Kurds' aid.

For Middle East Watch, a driving consideration over the past two years has been whether time would permit adequate research to be conducted to obtain reliable information that could both convince international public opinion and, later, satisfy a court of law. Although interim reports have previously been released about the Anfal1, with thepublication of this book, the first objective has been accomplished. Although there is persuasive evidence that virtually all are dead, whether the fate of the many tens of thousands of Kurdish civilians "disappeared" by government forces during 1988 can be definitively settled anytime soon remains to be seen. Much depends on the future course of internal Iraqi politics.

a system of cooperative federalism emerged, as the powers of the federal government expanded.
