By allowing IRIS Lavan to dock in Kochi citing 'technical problems' and providing humanitarian assistance to its crew, India signaled its commitment to international maritime conventions and humanitarian principles. This action reflects India's foreign policy of strategic autonomy, where it balances its relations with the US and other Western powers with its long-standing ties and strategic interests with Iran, without necessarily defying US sanctions directly but rather acting on humanitarian grounds.

The primary legal instrument is the Iran Sanctions Act (ISA), passed by the US Congress. It is a permanent law that provides a broad framework for sanctions. Presidential Executive Orders (EOs), on the other hand, are issued by the President and can be more flexible, allowing for quick responses to changing situations. However, EOs can be easily reversed by a subsequent President, making them less permanent than congressional laws like the ISA, which require legislative action to repeal or amend.

Secondary sanctions are potent because they extend US financial and economic power globally, compelling non-US entities to comply with US foreign policy objectives. They are controversial due to their extraterritorial nature, infringing on the sovereignty of other nations. Primary sanctions only restrict US persons. Secondary sanctions solve the problem of other countries continuing to trade with Iran, effectively isolating Iran from the global financial system and oil markets by threatening to cut off any entity, regardless of its nationality, from the US market if it deals with sanctioned Iranian sectors.

Critics argue that while humanitarian goods are technically exempt, the pervasive fear of secondary sanctions among international banks, shipping companies, and suppliers leads to 'over-compliance'. Financial institutions are reluctant to process any transactions involving Iran, even for exempt goods, to avoid potential penalties from the US Treasury's OFAC. This creates significant logistical and financial hurdles, making it extremely difficult for Iran to procure essential medicines, medical equipment, and food, directly impacting the health and well-being of ordinary Iranian citizens.

The US withdrawal from the JCPOA in 2018 fundamentally altered the sanctions regime by reinstating all previous US nuclear-related sanctions that had been lifted under the agreement. This move intensified economic pressure on Iran, cutting off its access to international oil markets and banking systems, which had seen some relief during the JCPOA. Globally, it strained relations between the US and its European allies (who wanted to preserve the deal), undermined the credibility of international agreements, and pushed Iran to gradually breach its commitments under the JCPOA, leading to renewed fears of nuclear proliferation.

The most direct impact is on Iran's oil export revenues. Before the 2018 sanctions reinstatement, Iran's oil exports reached over 2.5 million barrels per day, generating significant income. After the US withdrawal from the JCPOA and the re-imposition of sanctions, Iran's oil exports plummeted to as low as 200,000-300,000 barrels per day. This drastic reduction in revenue, from potentially tens of billions of dollars annually to a fraction, severely limits the Iranian government's budget, forcing cuts in social welfare programs, infrastructure projects, and its ability to fund regional proxy groups like the Houthis in Yemen or Hezbollah in Lebanon.

If US sanctions on Iran were suddenly lifted, Iran's economy would likely experience an immediate boost. Its oil exports would surge as it regains access to international markets, leading to increased government revenue. Iranian banks would reconnect with the global financial system, facilitating international trade and investment. Foreign companies, especially in the energy and automotive sectors, would likely rush to invest in Iran. This would lead to a stronger currency, lower inflation, improved living standards for ordinary citizens, and greater diplomatic engagement with the global community.

Critics argue that the extraterritorial application of US secondary sanctions infringes upon the national sovereignty of other countries by forcing their companies and citizens to abide by US foreign policy, even when their own national laws permit trade with Iran. This is seen as a violation of international law and a form of economic coercion. The US typically defends this practice by asserting that these sanctions are a necessary tool to achieve critical national security objectives, such as preventing nuclear proliferation and combating terrorism, when direct diplomatic or military actions are deemed insufficient or too risky. They argue that the global financial system's interconnectedness necessitates such measures to be effective.

India should adopt a multi-pronged approach. Firstly, continue diversifying its energy imports to reduce over-reliance on any single source, including exploring options like Russian oil (as recently seen with waivers) and increasing domestic production. Secondly, actively promote and invest in alternative trade routes like the International North-South Transport Corridor (INSTC) to bypass traditional chokepoints like the Strait of Hormuz and Red Sea. Thirdly, maintain robust diplomatic engagement with both the US and Iran, advocating for humanitarian trade exemptions and seeking long-term solutions that ensure regional stability and energy security for all. Lastly, leverage multilateral forums to build consensus against unilateral sanctions that impact global trade and humanitarian access.

The effectiveness of US sanctions is a subject of ongoing debate. Proponents argue that sanctions have significantly hampered Iran's nuclear program, leading to agreements like the JCPOA, and have reduced its financial capacity to support proxy groups. However, critics contend that sanctions often have unintended consequences: they can fuel anti-US sentiment, strengthen hardline elements within Iran by fostering a siege mentality, and push Iran to seek alternative, less transparent ways to advance its programs or support proxies. Furthermore, the economic hardship caused by sanctions can destabilize the region by creating humanitarian crises and fostering resentment, potentially leading to greater instability rather than compliance.
