India's decision to suspend the Indus Waters Treaty with Pakistan has significant consequences for Pakistan's water supply and power generation. The treaty, which divides the rivers of the Indus Basin between the two countries, has been a symbol of cooperation in their adversarial relationship. The suspension of the treaty could disrupt Pakistan's agricultural cycles, hydroelectric power generation, and food production, exacerbating its water scarcity. In response, Pakistan has suspended the Simla Agreement, leading to diplomatic tension. India's decision also reflects a strategic calculation to internationalize the cost of Pakistan's inaction on terrorism, potentially setting a precedent for hydro-politics worldwide.
