The Indo-Pakistani rivalry significantly constrains regional cooperation and forces other South Asian countries to navigate a complex geopolitical landscape. Smaller nations often have to balance their relationships with both India and Pakistan, avoiding actions that might be perceived as siding with one against the other. For example, Sri Lanka's engagement with China's Belt and Road Initiative is viewed with suspicion by India, partly due to India's concerns about Pakistan's close ties with China. Similarly, Nepal's relations with India are often viewed through the lens of Pakistan's influence in the region. This rivalry also hinders regional initiatives like SAARC, as disagreements between India and Pakistan often paralyze decision-making.

Critics argue that the preference for bilateralism in South Asian IR undermines regional cooperation and prevents the resolution of common challenges. By focusing on individual negotiations, countries miss out on the benefits of collective action and risk exacerbating existing tensions. For example, water disputes could be more effectively managed through a regional framework rather than separate bilateral talks. In response, one could argue that bilateralism is often a pragmatic necessity given the deep-seated mistrust and political complexities within the region. While a regional approach is desirable, it may be unrealistic in the short term due to the lack of consensus and the dominance of bilateral issues like the Indo-Pakistani rivalry.

Extra-regional powers introduce new dynamics and strategic considerations into South Asian IR. China's growing economic and strategic influence, particularly through the Belt and Road Initiative, challenges India's traditional dominance in the region. The United States' involvement, often driven by counter-terrorism concerns and strategic partnerships, further complicates the landscape. For India, this means navigating a multi-polar environment where it must balance its own interests with the influence of these external actors. It also requires India to strengthen its own regional partnerships and develop strategies to counter China's growing presence. The US support for Pakistan's right to defend itself against cross-border attacks from Afghanistan further complicates India's strategic calculations.

The Indus Waters Treaty between India and Pakistan is significant because it is a rare example of successful cooperation in managing shared water resources despite ongoing political tensions. It allocates the waters of the Indus River system between the two countries and establishes a mechanism for resolving disputes. However, the treaty still faces challenges due to climate change, which is altering river flows, and increasing demands for water due to population growth and agricultural needs. Furthermore, political tensions can undermine the treaty's implementation, as seen in occasional disputes over specific projects or alleged violations. The treaty's success is often cited as a model for water cooperation, but its limitations highlight the difficulties of maintaining such agreements in a conflict-prone region.
