In south Asia, India occupies a pivotal position in the region due to its geographical size, location, economic & industrial base, technological advances, military strength and foreign policy.  India's democratic strength is superior, leadership is capable & firm determinant.  Except India, in south asia region, there are two types of states, (i)  Larger countries like Pakistan and (ii) smaller countries like Nepal, Bhutan, Bangladesh, Sri Lanka and Maldives.  Pakistan is larger country and is rich of natural resources.  Pakistan has ability to limit the Indian hegemonic and influence in the region. But Pakistan's own limitations come from its geographic location, economic and military potentials. Pakistan has witnessed several military regime and mass radicalization under the influence of Islamic West Asian Countries.  Lack of Civil Authority, control over terrorist organization, poor foreign policy cause poor bargaining power in the region.   Pakistan does not have ability to substitute India as the leader of the region but it can bargain for share in leadership under the influence of external powers. The smaller countries have limited resources and they can not pose problem to Indian leadership in the region. They can pose problems through extra regional intervention, or their own internal instability.  The power relationships in South Asia are affected by the intrusive powers of the United States, Russia, China and others are influencing policies for their own benefits and positing problems by un-respecting the sovereignty of the countries.
