巴基斯坦和印度可能因水而開戰

印度河水權成為新紅線　南亞兩個核武國家再陷危險對峙

印度與巴基斯坦之間長達數十年的宿怨，如今正出現一個更加令人憂心的新戰場——水。

巴基斯坦總理夏巴茲・謝里夫近日公開向印度發出強硬警告，稱「每一滴水都是我們的紅線」，並表示如果印度威脅巴基斯坦的水源，巴方將作出直接回應。這番話使原本屬於水資源與外交層面的爭端，再一次蒙上軍事衝突的陰影。(AP News⁠)

印巴水權爭端的核心，是1960年在世界銀行協助下簽署的《印度河用水條約》。這項條約將印度河水系六條主要河流的使用權作出安排：印度主要使用拉維河、比亞斯河和薩特萊傑河等東部河流；巴基斯坦則主要依靠印度河、傑赫勒姆河和奇納布河等西部河流。數十年來，即使兩國經歷戰爭與嚴重政治危機，這項條約仍基本維持運作。(Reuters⁠)

然而，2025年4月克什米爾帕哈爾加姆發生造成26人死亡的襲擊後，印度指責巴基斯坦支持的武裝分子涉案，巴基斯坦則否認相關指控。印度隨後宣布將《印度河用水條約》置於暫停狀態。兩國關係急劇惡化，並於2025年5月爆發導彈、無人機等軍事交火，數日後才停火。(AP News⁠)

到了2026年，水資源問題並沒有隨著軍事停火而降溫。

巴基斯坦政府今年6月再次警告，任何企圖剝奪巴基斯坦依照條約應有水量的行動，都可能被視為將「水武器化」，並可能對南亞地區和平與安全造成嚴重後果。巴方也重申，若印度停止或轉移屬於巴基斯坦的水流，可能被視為「戰爭行為」。(AP News⁠)

對巴基斯坦而言，這絕非一般外交爭執。

印度河水系是巴基斯坦農業、糧食生產、水力發電以及數以百萬計人民生活的重要命脈。印度位於多條河流上游，因此任何大型水壩、蓄水、改變流量或水文資料合作的變化，都可能直接影響下游的巴基斯坦。另一方面，印度則長期將水資源合作與跨境恐怖主義問題聯繫起來，表示在巴基斯坦沒有可信且不可逆轉地停止其所指控的跨境恐怖主義支持之前，條約將繼續處於擱置狀態。(Reuters⁠)

問題因此變得極為危險：

對印度而言，這是國家安全問題；對巴基斯坦而言，這是國家生存問題。

當安全與生存兩種「紅線」相遇，任何誤判都可能造成無法控制的後果。

印度和巴基斯坦都是擁有核武器的國家。2025年的軍事衝突已經證明，兩國之間一次恐怖襲擊或邊境危機，都可能在極短時間內升級。如今，如果水源再成為新的戰略武器，南亞局勢將增加另一個極為敏感而危險的引爆點。

當然，目前仍不能斷言印度和巴基斯坦一定會「為水而戰」。印度現階段要完全截斷流向巴基斯坦的大河水量，也受到地理、水庫容量及基礎設施等現實條件限制。(Reuters⁠)

但是，比真正「斷水」更值得警惕的，是水已經逐漸成為兩國政治、外交和國家安全對抗的一部分。

世界進入氣候變遷、水資源短缺和人口快速增長的時代，未來國與國之間的衝突，未必只是為石油、土地或疆界，也可能是為了一條河、一座水壩，以及人民生存所需要的一滴水。

印巴兩國今天面對的問題，也許正是全世界的一個警告：

水原本應該滋養生命，不能讓它成為戰爭的導火線。

對印度和巴基斯坦而言，重新建立水資源談判與危機溝通機制，不只是外交上的選擇，更可能關係到南亞數十億人民的和平與未來。

Pakistan and India Could Go to War Over Water

Indus River Dispute Becomes a New Red Line as Two Nuclear-Armed Neighbors Face Rising Tensions

Saturday, August 15, 2026

The decades-long rivalry between India and Pakistan is now confronting a new and increasingly dangerous battlefield: water.

Pakistani Prime Minister Shehbaz Sharif recently issued a strong warning to India, declaring that “every drop of water is our red line.” He said Pakistan would respond directly if India threatened the country’s water supply. His remarks have transformed what was once largely a diplomatic and resource-management dispute into an issue carrying the risk of military confrontation.

At the center of the dispute is the Indus Waters Treaty, signed in 1960 with the assistance of the World Bank. Under the agreement, the six major rivers of the Indus River system were divided for use by the two countries. India was given primary rights over the eastern rivers—the Ravi, Beas, and Sutlej—while Pakistan received primary rights over the western rivers—the Indus, Jhelum, and Chenab.

For more than six decades, the treaty survived wars, border clashes, and repeated political crises between the two countries. It was often regarded as one of the rare examples of successful cooperation between India and Pakistan.

That stability, however, has now been seriously weakened.

Following the deadly attack in Pahalgam, Kashmir, in April 2025, which killed 26 people, India accused Pakistan-backed militants of involvement. Pakistan denied the allegations. India subsequently announced that it was placing the Indus Waters Treaty in abeyance.

Relations deteriorated rapidly. In May 2025, the two countries exchanged missile, drone, and other military strikes before eventually agreeing to a ceasefire.

But the ceasefire did not resolve the water dispute.

In 2026, Pakistan again warned that any attempt to deny it the water allocated under the treaty could amount to the “weaponization of water” and threaten peace and security throughout South Asia. Pakistani officials have stated that any serious attempt to stop or divert water belonging to Pakistan could be regarded as an act of war.

For Pakistan, this is far more than a diplomatic disagreement.

The Indus River system is the lifeline of the country. It supports agriculture, food production, hydroelectric power, industry, and the daily lives of millions of people. Much of Pakistan’s farming economy depends on water flowing through the Indus basin.

India, meanwhile, is located upstream on several of these rivers. That gives New Delhi significant strategic importance in the management of dams, reservoirs, river flows, and hydrological information.

India argues that cooperation over water cannot be separated from national security. New Delhi has maintained that the treaty will remain suspended until Pakistan credibly and irreversibly ends what India describes as its support for cross-border terrorism.

Pakistan rejects those accusations and insists that India has no right to unilaterally suspend an international water agreement.

This is what makes the present confrontation so dangerous.

For India, the issue has become one of national security.
For Pakistan, it has become one of national survival.

When one country’s security red line meets another country’s survival red line, even a small miscalculation can have enormous consequences.

India and Pakistan are both nuclear-armed nations. The military confrontation of 2025 demonstrated how quickly a terrorist attack or border crisis can escalate into direct military action.

If water now becomes another strategic weapon, South Asia will face an additional and potentially even more dangerous flashpoint.

At this stage, it would be an exaggeration to say that India and Pakistan are certain to go to war over water. Geography, reservoir capacity, engineering limitations, and international pressure all limit India’s ability to simply shut off the major rivers flowing into Pakistan.

But the greater danger is not necessarily the immediate possibility of completely stopping the water.

The greater danger is that water itself is becoming part of the political, diplomatic, and military confrontation between the two countries.

The world is entering an era of climate change, population growth, extreme weather, and increasing pressure on limited water resources. Future conflicts between nations may no longer be fought only over oil, territory, ideology, or borders.

They may also be fought over a river, a dam, a reservoir—or simply over access to a single drop of water.

The growing India-Pakistan water dispute therefore carries a warning far beyond South Asia.

Water should sustain life. It must never be allowed to become the trigger for war.

For India and Pakistan, restoring meaningful dialogue, strengthening water-management mechanisms, and maintaining direct crisis communications are no longer merely diplomatic choices.

They may be essential to protecting the peace and future of hundreds of millions of people across South Asia.
