American policies towards South Asia have been inconsistent at best and neglectful at worst since the 1947 partition of India. The United States should therefore seize the window of opportunity provided by the political events of 2013-2015 and invest in improved diplomatic, economic, and military relationships with both India and Pakistan. The relationship between these two countries will largely determine the security and prosperity of not only Asia, but also the entire world in the 21st Century. The United States should therefore rebalance towards India and Pakistan, not the greater Asia-Pacific region, to better protect core national interests and those of its allies and key partners. The United States and China should seek common ground to facilitate a more stable South Asia based upon economic interdependence, transparent diplomacy, and mutual security objectives.
