Iran War and Lessons for Bangladesh: The Need for National Security Preparedness
The ongoing conflict involving Iran, the United States, and Israel has emerged as one of the most significant geopolitical crises of recent times. It is not merely a regional war; rather, it represents a complex interplay of nuclear politics, great power rivalry, intelligence warfare, and strategic resilience. For countries like Bangladesh, this conflict offers important lessons-particularly in the areas of national security, sovereignty, and future preparedness. Iran has been under international sanctions for many years. Since the early 2000s, strict economic restrictions have been imposed on the country over its nuclear program. As a result, Iran’s economy has suffered significantly-oil exports have declined, financial transactions have been restricted, inflation has risen, and the national currency has depreciated. Despite these challenges, Iran has continued its nuclear program, maintaining that it is intended for peaceful purposes, particularly for electricity generation.
Under the 2015 nuclear agreement (JCPOA), Iran agreed to limit its nuclear activities. However, after the United States withdrew from the deal and reimposed sanctions, Iran resumed and accelerated uranium enrichment. By 2025, Iran had enriched uranium up to approximately 60 percent, which is considered close to weapons-grade level. Iran has repeatedly declared that it does not seek nuclear weapons and has stated, based on its religious position, that such weapons are against humanity. However, the United States and Israel have viewed these claims with skepticism and have considered Iran’s capabilities as a potential threat. This tension eventually escalated into open conflict. In 2025, Israel launched strikes targeting Iran’s nuclear and military facilities, and the United States later joined the attacks. Key sites such as Fordow, Natanz, and Isfahan became primary targets. The conflict then expanded further, with both sides engaging in missile and drone attacks.
On 28 February 2026, the United States and Israel again carried out coordinated strikes on Iran, even while negotiations were ongoing. The objective of these attacks was to weaken Iran’s nuclear capability and damage its military infrastructure. However, Iran responded swiftly, demonstrating strong resistance through its missile and drone capabilities.
Many had initially assumed that the conflict would be short-lived-like the wars in Iraq (2003) or Libya (2011). However, Iran has proven those assumptions wrong. The conflict has turned into a prolonged and complex war. Iran has demonstrated remarkable proficiency in asymmetric warfare, particularly in missile and drone technology, surprising many observers around the world.
Another important dimension of this war is intelligence warfare. Israel’s intelligence agency, Mossad, had over the years developed an extensive network inside Iran. Through this network, it was able to gather critical intelligence, identify targets, and conduct sabotage operations. This demonstrates that modern warfare is no longer confined to the battlefield alone-it extends into cyber, intelligence, and psychological domains as well.
In this context, there are several important lessons for Bangladesh.
First, strategic autonomy is the foundation of a state’s survival. In today’s global order, excessive dependence on any single power limits a country’s decision-making freedom. Iran’s experience shows that when a country faces international pressure, sanctions, diplomatic isolation, and economic coercion can significantly weaken it. Therefore, Bangladesh must pursue a balanced and multi-dimensional foreign policy-maintaining relations with both regional and global powers but avoiding dependence on any single actor. The principle of “friendship with all, dependence on none” can serve as the cornerstone of long-term security.
Second, building indigenous defense capability is essential in the modern era. Despite decades of sanctions, Iran has developed its own missile, drone, and defense technologies, which have enhanced its deterrence capability. Bangladesh, even within its limited budget, must move toward technology-driven defense modernization. Air Defense (AD) systems are critical for protecting national airspace. Electronic Warfare (EW) has become a decisive factor in modern conflict-disrupting enemy communications while securing one’s own. Drone and counter-drone technologies are central to future warfare. Missile capability provides a credible deterrent, discouraging potential aggression. In addition, cyber security has become an integral part of national defense, as modern conflicts are fought not only on land but also across digital networks and information systems.
Third, intelligence and counter-intelligence capabilities form the backbone of national security. Iran’s experience illustrates that before external attacks, internal vulnerabilities are often created through intelligence penetration, data collection, and target identification. If a state cannot secure its internal environment, its external defense mechanisms become ineffective. Bangladesh therefore needs to develop a modern, integrated intelligence system-combining Human Intelligence (HUMINT), Signals Intelligence (SIGINT), and cyber intelligence-along with a strong counter-intelligence framework to prevent foreign infiltration.
Fourth, asymmetric warfare is an effective strategy for small and medium-sized states. Direct military competition with major powers is unrealistic, but deterrence can be built through technology, mobility, and innovation. Iran has developed a robust deterrence posture using missiles, drones, proxy networks, and rapid strike capabilities. Bangladesh can similarly strengthen its deterrence by focusing on coastal defense, rapidly deployable forces, mobile missile systems, and network-centric warfare strategies.
Fifth, without economic stability, national security cannot be sustained. Although sanctions have weakened Iran’s economy, it has managed to endure through internal capacity and resource management. This offers an important lesson for Bangladesh-economic diversification, industrialization, energy security, and expansion of export markets are essential. A strong economy enables a country to sustain defense expenditures and withstand external pressures.
Sixth, national unity is the greatest strength of any country. If a nation is internally divided, external powers can exploit that weakness. Despite prolonged conflict, Iran has been able to maintain a certain level of national cohesion, which has strengthened its resistance capability. For Bangladesh, political stability, social harmony, and a unified stance on national interests are crucial.
Seventh, the nature of modern warfare has fundamentally changed. It is no longer short-term or limited; rather, it is prolonged, multi-dimensional, and technology driven. Military, economic, cyber, informational, and diplomatic domains now operate simultaneously. Therefore, Bangladesh must adopt long-term planning, strategic thinking, and forward-looking preparedness.
Finally, it must be understood that a nation’s independence is not ensured merely through political declaration. It must be safeguarded through military strength, economic capacity, technological advancement, and national unity. Iran’s experience teaches us that a country can withstand even the most adverse conditions if it is prepared. For Bangladesh, this lesson is critically important-because security is not a static condition; it is a continuous process that must be ensured through awareness, planning, and capability development. Geopolitical awareness is essential. Bangladesh is in a strategically sensitive region, influenced by both regional and global powers. Therefore, it is imperative to plan with future risks in mind. The Iran conflict is not just a war-it is a real lesson in modern warfare and state resilience. It demonstrates that with preparation, technology, and national unity, a country can survive even under severe challenges. The message for Bangladesh is clear: sovereignty must be protected through preparedness. Preparation must be undertaken in times of peace, because in times of crisis, there is no substitute for readiness. This is not a lesson of conflict-it is a lesson of preparedness.
