Bangladesh-U.S. MoU on Civil Nuclear Cooperation; Both NPT Parties with IAEA Safeguards

Bangladesh and the US signed a strategic MoU on civil nuclear cooperation in New York on September 25, 2026, aiming to expand the Rooppur nuclear plant. This strengthens US-Bangladesh ties and reinforces the global nuclear non-proliferation regime, as both countries are NPT parties with IAEA safeguards in force. For UPSC aspirants, this is a key example of international energy cooperation and its implications for India's neighbourhood.

US-Iran War: Trump Rejects 7-Day Peace Deal; Strait of Hormuz, Nuclear Talks at Stake

US President Donald Trump has rejected Iran's seven-day peace proposal to end the war, reopen the Strait of Hormuz, and begin nuclear talks. The proposal, mirroring the June 2026 MoU, was announced at the UNGA. The rejection escalates tensions in the Gulf, impacting global oil flows and regional stability. For UPSC aspirants, this is crucial for understanding Iran-US dynamics, strategic chokepoints, and the role of the Strait of Hormuz in global energy security.

US-Saudi Civil Nuclear Pact Submitted to Congress for 90-Day Review Under Atomic Energy Act

The US has submitted a civil nuclear agreement with Saudi Arabia to Congress for a mandatory 90-day review under the Atomic Energy Act.

BRICS New Delhi Declaration Flags Nuclear Safety; Bloc Expands to 10 Members Under India's Chair

BRICS leaders adopted the New Delhi Declaration at the 2026 summit hosted by India, expressing serious concern over deliberate attacks on civilian nuclear facilities under IAEA safeguards and the growing risks of nuclear conflict. The declaration also highlights BRICS expansion (10 members, 10 partner countries) and reaffirms support for nuclear-weapon-free zones. For UPSC aspirants, this is a key data point on India's diplomatic leadership, nuclear disarmament discourse, and the evolving BRICS architecture.

US Lindsey O. Graham Act Sanctions Russian Oil, Exempts Low-Enriched Uranium Imports for Nuclear Reactors

The US signed a law imposing up to 100% tariffs on importers of Russian oil/gas, but exempts its own imports of low-enriched uranium from Russia. This exposes a strategic contradiction: while pressuring India and China, the US relies on Russia for 20% of its nuclear fuel needs. For India, which sources 45% of its oil from Russia, this law poses a direct challenge to its energy security.

US-Saudi 123 Nuclear Deal Allows Enrichment, Weakens Nonproliferation Order

The US-Saudi 123 Agreement permits uranium enrichment on Saudi soil, breaking from the gold-standard 2009 UAE deal. This weakens global nonproliferation norms, risks a Middle East nuclear arms race, and undermines US credibility, especially after the US-Israel war on Iran.

US-Iran Ceasefire Expires: 14-Point Framework, Strait of Hormuz Deadlock & Nuclear Stalemate

The 60-day US-Iran ceasefire (signed June 17, 2026) has expired without progress. The deal collapsed over control of the Strait of Hormuz, which ships 20% of global oil. This is critical for UPSC: tests geopolitics, energy security, and nuclear non-proliferation.
