A stable, democratic, prosperous Pakistan actively combating religious militancy is considered vital to U.S. interests. U.S. concerns regarding Pakistan include regional and global terrorism, efforts to stabilise neighbouring Afghanistan, nuclear weapons proliferation, the Kashmir problem and Pakistan-India tensions, democratisation and human rights protection, and economic development. Pakistan is praised by U.S. leaders for its ongoing co-operation with U.S.-led counter-terrorism and counterinsurgency efforts, although long-held doubts exist about Islamabad's commitment to some core U.S. interests. A mixed record on battling Islamist extremism includes ongoing apparent tolerance of Taliban elements operating from its territory, although some evidence from early 2010 suggests a possible shift here. This book reviews key current issues and developments in Pakistan and in U.S.-Pakistan relations.
