Iran Approves Closure of Strait of Hormuz After U.S. Strikes on Nuclear Sites

Source: The Hindu

Syllabus: GS Paper II (International Relations)

IN NEWS 

  • In a major escalation of the ongoing conflict, Iran has reportedly approved the closure of the Strait of Hormuz. This decision comes immediately after the United States carried out air strikes on three nuclear sites within Iran, as described by President Trump as a "spectacular success." 
  • The approval to close the vital Strait signifies a critical escalation, with profound implications for global energy markets and regional stability.

Context of Iran's Decision

Iran's approval to close the Strait of Hormuz is a direct and retaliatory response to the U.S. military strikes on its nuclear facilities.

  • U.S. Strikes: The United States carried out strikes on three Iranian nuclear sites, indicating a clear intent to target Iran's nuclear capabilities. President Trump's statement of "spectacular success" underscores the significance of these military actions.
  • Escalation: These U.S. strikes represent a direct military action against Iranian territory, escalating the long-standing tensions between the two nations from proxy conflicts and cyber warfare to overt military confrontation.
  • Retaliatory Measure: Iran's decision to close the Strait of Hormuz is a severe retaliatory measure, leveraging its geographical advantage to exert economic pressure and demonstrate its capacity to disrupt global systems.

What is the Strait of Hormuz? 

The Strait of Hormuz is a highly strategic and narrow waterway connecting the Persian Gulf with the Gulf of Oman and, subsequently, the Arabian Sea.

  • Global Significance: It is one of the world's most critical maritime chokepoints for oil transit.
  • Oil Transit Volume: According to the U.S. Energy Information Administration (EIA) and the International Energy Agency (IEA), the Strait handles approximately million barrels of oil per day, accounting for roughly 20% of global petroleum liquid consumption.
  • Key Exporters: It is the primary route for oil exports from major Middle Eastern producers including Saudi Arabia, UAE, Kuwait, Iraq, Iran, and Qatar.
  • Asian Markets: A vast majority (84% of crude oil and 83% of LNG) passing through this Strait is destined for Asian countries, making its unhindered passage vital for their energy security.

Implications of Closure

Iran's approval to close the Strait, if implemented, would have immediate and severe global implications:

  • Global Energy Crisis: A direct halt or severe disruption of oil transit would trigger an unprecedented global energy crisis, leading to a dramatic spike in crude oil prices (as seen in the earlier news of Brent crude rising), fuel shortages, and economic instability worldwide.
  • Increased Shipping Costs: Even without full closure, the threat and perceived risk would cause shipping and insurance costs for vessels operating in the region to skyrocket.
  • Disruption of Trade Routes: It would force oil tankers and other commercial vessels to seek much longer and more expensive alternative routes, distorting global trade and supply chains.
  • Military Confrontation: Any attempt by Iran to physically close the Strait would almost certainly provoke a direct military response from the U.S. and its allies, who are committed to ensuring freedom of navigation through international waterways. This would lead to a full-blown military conflict in the region.
  • Impact on India: India, which imports over 80% of its crude oil requirements and relies heavily on Middle Eastern sources, would be severely impacted by such a closure. It would lead to massive import bill hikes, increased inflation, and significant pressure on its fiscal and current account deficits.

Background of Iran's Nuclear Program and U.S. Concerns

  • Iranian Nuclear Program: Iran has maintained a nuclear program, which it insists is for peaceful energy purposes. However, the international community, particularly the U.S. and Israel, has expressed grave concerns that it could be used to develop nuclear weapons.
  • Joint Comprehensive Plan of Action (JCPOA): The 2015 nuclear deal (JCPOA) placed limits on Iran's nuclear activities in exchange for sanctions relief. However, the U.S. withdrew from this deal in 2018 under the Trump administration and reimposed sanctions.
  • U.S. Policy: The U.S. policy under President Trump has been one of "maximum pressure" on Iran, aiming to curb its nuclear ambitions, ballistic missile program, and support for regional proxies. The recent strikes align with this assertive stance.

US carries out strikes on three nuclear sites in Iran

Source: The Hindu

Syllabus: GS Paper II (International Relations)

IN NEWS 

  • The United States has carried out targeted air strikes on three nuclear sites within Iran. President Trump described these military operations as a "spectacular success." 
  • These strikes mark a significant escalation in the tensions between Washington and Tehran, directly targeting Iran's nuclear infrastructure.

Context of the Strikes

The U.S. air strikes on Iranian nuclear facilities represent a direct military confrontation, escalating the long-standing adversarial relationship between the two nations. This action follows years of heightened tensions, economic sanctions, and proxy conflicts.

  • Targeting Nuclear Infrastructure: The deliberate targeting of nuclear sites suggests a U.S. objective to directly impede or set back Iran's nuclear program, which the U.S. and its allies view with suspicion, fearing it could lead to the development of nuclear weapons.
  • Assertion of Force: The strikes convey a strong message of deterrence and demonstrate the U.S.'s willingness to use military force to achieve its strategic objectives regarding Iran.
  • President Trump's Stance: President Trump's description of the strikes as a "spectacular success" underlines the decisive nature of the operation from the U.S. perspective and aims to project strength and resolve.

Iranian Nuclear Program (Background)

  • Purpose: Iran has always asserted that its nuclear program is purely for peaceful purposes, primarily for energy generation and medical applications.
  • International Concerns: Despite Iran's claims, many nations, particularly the U.S. and Israel, have expressed deep concerns about the program's potential military dimension, especially regarding uranium enrichment levels and the development of related technologies.
  • Joint Comprehensive Plan of Action (JCPOA): Signed in 2015, this international agreement placed restrictions on Iran's nuclear activities in exchange for sanctions relief. However, the U.S. unilaterally withdrew from the JCPOA in 2018 under the Trump administration, reimposing stringent sanctions. This withdrawal often led to Iran gradually reducing its compliance with the deal's restrictions.
  • IAEA Monitoring: The International Atomic Energy Agency (IAEA) is responsible for monitoring Iran's nuclear activities, but its access and oversight have sometimes been contentious amidst political tensions.

Implications of the U.S. Strikes

The U.S. strikes carry profound and immediate implications for regional and global dynamics:

  • Escalation of Conflict: This is a direct military action against sovereign territory, moving the U.S.-Iran standoff into an overt, dangerous phase. It significantly raises the risk of a full-blown war in the Middle East.
  • Iran's Retaliation: As seen in related news (Iran approving closure of Strait of Hormuz), Iran is likely to retaliate, potentially through military means, cyberattacks, or by activating its regional proxies, further destabilizing the region.
  • Global Energy Markets: The strikes and potential Iranian retaliation (e.g., closing the Strait of Hormuz) will have an immediate and severe impact on global crude oil prices, supply chains, and overall economic stability.
  • International Diplomacy: It puts immense pressure on international bodies and other major powers to de-escalate the situation and prevent a wider conflict. Diplomacy becomes critically challenging in such a highly charged environment.
  • Regional Security: The strikes will likely intensify the security dilemma in the Middle East, potentially leading to increased militarization and proxy confrontations.
  • Nuclear Proliferation Concerns: Depending on the damage inflicted and Iran's response, the incident could either set back Iran's nuclear program or, paradoxically, accelerate its determination to develop nuclear weapons as a deterrent.
