The UK Department for Energy Security and Net Zero confirmed the incident but said there was no risk to the wider energy system [21]. A technical cybersecurity analysis argued the four-day outage was a deliberate demonstration of IRGC-linked capability to reach British generation assets rather than an attempt to cause harm, framing the UK attack alongside US water-sector intrusions as a coordinated campaign against Western utility infrastructure [29]. Iran International's Persian-language service reported the attack coincided with intrusions on US water infrastructure and that Iran has expanded cyber operations since February [30]. National Cyber Security Centre chief executive Richard Horne warned that hostile states including Russia, China, and Iran are increasingly targeting systems behind the UK's key services [21][22].

President Donald Trump called it "the most crushing economic operation ever taken against any country" and warned of "tremendous economic consequences" for any country providing Iran an economic lifeline [2][4][9].

Rezaei stated that Iran had breached the US naval blockade by shipping 70 million barrels of oil in recent months [10][33].
Iranian Foreign Minister Abbas Araghchi dismissed the sanctions as a sign of desperation, saying Washington's shift from military operations to old sanctions plans showed they are desperate and that all their actions have failed [5][9][23]. Foreign Ministry spokesperson Esmaeil Baghaei called the secondary sanctions an assertion of US extraterritorial sovereignty over every independent UN member state, saying they find no foundation in international law and violate the principle of sovereign equality under the UN Charter [2][4][12][20]. President Masoud Pezeshkian called for ending the war "today, when we are powerful and have dignity," while acknowledging that Iranian society faces "many difficulties" [5][9][15].

Iranian officials announced the discovery of new gas reserves in Fars province exceeding 160 billion cubic meters of extractable gas, with Petroleum Minister Mohsen Paknejad noting the gas is sweet and free of hydrogen sulfide, reducing exploitation costs [15].

Commodity data from Kpler showed Iran's crude loadings collapsing from 893,000 barrels per day in July to 156,000 barrels per day through August 17 [43]. US Energy Secretary Chris Wright stated the US military helped move a seven-day average of 8 million barrels per day through the strait, down from more than 20 million before the war [12].

Iran researcher Hamidreza Azizi of the Clingendael Institute described Tehran's shift toward "early deterrence," where even attack preparations could trigger retaliation, as part of a new offensive doctrine of preemption and disproportionate response [10][17][19]. Armed Forces Chief of Staff Ali Abdollahi showcased underground missile production and promised "crushing, punishing and devastating responses" to any threat [12]. VnExpress reported that analysts warn an Iranian attack on a NATO member could trigger Article 4 or Article 5, potentially giving Washington an advantage in building a European coalition [25]. An analysis from Infobae described the consolidation of power by IRGC military leaders following the death of Supreme Leader Ali Khamenei, with new billboards in Tehran featuring security-focused figures and transforming the Islamic Republic's character [27].

South Korea is weighing its first-ever military contribution to Hormuz security after US pressure, while Japan is advancing alternative crude-oil procurement routes bypassing the strait [36][37]. Reports describe Iran bypassing the naval blockade via overland routes through Pakistan and Central Asia, and India moving to hand over Chabahar port operations to Iran to avoid its own banks being sanctioned [38][39]. African nations reported fuel rationing, price surges, and route disruptions tied to the Hormuz standoff, with governments in Kenya, Ethiopia, and Cape Verde taking emergency measures to protect supply and households [41].
Chinese Foreign Ministry spokesperson Lin Jian said sanctions and pressure will not help resolve the issue and called for political and diplomatic means [6]. European geopolitical institute specialist Sébastien Boussois doubted sanctions would collapse the regime, saying no historical example exists [15]. Lancaster University professor Simon Mabon argued that Gulf countries cannot change geography and must live alongside Iran, suggesting some Gulf states pushed for harder strikes to weaken IRGC hardliners rather than precipitate regime collapse [19]. RBC analyst Helima Croft questioned whether more sanctions will change Iran's behavior, noting Tehran appears to believe it can outlast the US [42]. Quincy Institute executive vice president Trita Parsi said no nation in the region can afford another long war and that depleted global oil inventories make prolonged confrontation unattractive [19].
