The Boomerang Effect: How India's Destabilization Strategy Will Backfire on the Seven Sisters

By undermining Bangladesh, New Delhi risks reigniting the very insurgencies it spent decades pacifying

Key Findings

On December 15, 2024, Hasnat Abdullah—a leader of Bangladesh’s National Citizen Party—issued a warning that should have alarmed strategic planners in New Delhi: “Since you are housing those who destabilize us, we will give refuge to the separatists of seven sisters too.”

The statement was inflammatory, perhaps reckless. But it illuminated a fundamental truth that India’s current Bangladesh policy ignores: destabilization is a game two can play, and India has far more to lose.

The Forgotten Bargain

For fifteen years under Sheikh Hasina, Bangladesh served as India’s most reliable security partner in the region. This was not altruism—it was a strategic bargain. In exchange for India’s support of her increasingly authoritarian rule, Hasina delivered something invaluable: the systematic dismantling of anti-India insurgent networks operating from Bangladeshi soil.

The results were substantial:

Insurgent Group Bangladesh Action Impact on India
ULFA Camps dismantled; leaders extradited Assam insurgency significantly weakened
NSCN factions Transit routes disrupted Nagaland violence reduced
Bodo militants Safe havens eliminated BTAD region stabilized
Multiple NE groups Intelligence sharing established Preemptive operations enabled

The 2024 Tripura Peace Accord—ending a 35-year insurgency—was only possible because Bangladesh had systematically denied sanctuary to militants. When the last 328 NLFT and ATTF fighters surrendered, it marked the culmination of Indo-Bangladesh security cooperation.

That cooperation ended on August 5, 2024, when Hasina fled to India.

The Chittagong Calculation

Reports of Indian involvement in Bangladesh’s Chittagong Hill Tracts have circulated for years. The Kuki-Chin National Front (KNF)—a separatist movement seeking autonomy for ethnic Kuki-Chin peoples in Bandarban and Rangamati—has documented connections to militant networks in India’s Manipur.

The ethnic geography is significant: Kuki-Chin peoples inhabit a contiguous zone spanning:

In the first batch of KNF fighters, over a hundred members were reportedly sent to Manipur for training. The collaboration continues—in March 2024, India’s Assam Rifles detained two Kuki-Chin National Army members in Mizoram.

The May 2025 Seizure

In May 2025, Bangladeshi authorities seized over 20,000 combat-style uniforms from a garment factory in Chittagong. Police linked the consignment to the KNF—raising questions about the scale of the insurgent infrastructure being developed and who might be financing it.

If India believes it can support separatism in Bangladesh’s southeast without consequence, it fundamentally misunderstands the dynamics it is unleashing.

The Boomerang Trajectory

The same ethnic networks that allegedly channel support to KNF can reverse direction. Consider the arithmetic:

What India gains from CHT destabilization:

What India risks:

The insurgencies that consumed India’s Northeast for decades were never fully defeated—they were contained through a combination of military pressure, political accommodation, and crucially, Bangladesh’s cooperation. Remove that cooperation, and the containment unravels.

The Siliguri Vulnerability

India’s strategic planners understand the Siliguri Corridor problem intimately. This narrow strip of territory—barely 22 kilometers wide at its narrowest point—connects India’s seven northeastern states to the mainland. It is bordered by Nepal, Bangladesh, and Bhutan.

During the decades of active insurgency, militants exploited this geographic vulnerability relentlessly. The corridor can be interdicted, infiltrated, or simply threatened in ways that impose enormous costs on India’s ability to project power in its own territory.

Abdullah’s reference to the “seven sisters” was not geographically ignorant—it was strategically pointed. A Bangladesh that actively supports Northeast insurgents could:

  1. Provide sanctuary for militant leadership and training camps
  2. Enable transit for weapons, fighters, and supplies
  3. Offer intelligence on Indian military deployments and vulnerabilities
  4. Coordinate operations across the porous border

None of this requires Bangladesh to formally support insurgency. Mere tolerance—the withdrawal of active suppression—would suffice to transform India’s security environment.

The Strategic Inversion

The irony is profound. India’s alleged destabilization strategy in Bangladesh is designed to weaken a neighbor that New Delhi perceives as drifting from its orbit. But the strategy guarantees the very outcome it seeks to prevent.

A destabilized Bangladesh:

A stable, prosperous Bangladesh with normalized relations:

India’s current approach inverts this logic entirely.

The Historical Lesson

Pakistan learned this lesson in Afghanistan. For decades, Islamabad believed it could use militant proxies as instruments of strategic depth—supporting groups that would serve Pakistani interests in Kabul while remaining controllable. The result was the Tehrik-i-Taliban Pakistan, which turned the same networks, training, and ideology against the Pakistani state itself.

The “strategic depth” doctrine produced not security but perpetual insecurity—a lesson written in the blood of tens of thousands of Pakistani civilians and soldiers.

India appears determined to repeat this error on its eastern flank. The militants being cultivated today, the separatist networks being tolerated or encouraged, the destabilization being pursued—all of it can reverse direction. The boomerang always returns.

The Bottom Line

India’s destabilization strategy against Bangladesh is not merely immoral—it is strategically suicidal. The security cooperation that pacified the Northeast cannot survive the relationship India is destroying. When the insurgencies revive—and they will—New Delhi will have no one to blame but itself. The choice is stark: a stable Bangladesh as a security partner, or a hostile Bangladesh as a sanctuary for the very forces India spent decades defeating.
