US Naval Blockade: President Trump affirmed the continuation of the blockade on Iranian ports, claiming it costs Iran $500 million daily, intensifying economic pressure.
Iran's Military Posture: Parliament Speaker Ghalibaf warned of 'new cards' if war resumes, indicating Tehran's readiness for escalation amid ceasefire uncertainties.
[GS3-Economy] The Iran conflict is reshaping global aviation economics, with potential long-term impacts on flight routes, fuel costs, and airline operations.
Lebanon-Israel Talks: US-hosted negotiations aim to end hostilities, but face opposition from Iran-backed Hezbollah, complicating regional stability efforts.

[GS2-International Relations] The dollar's fluctuation against the euro reflects market optimism for a ceasefire, underscoring the economic ripple effects of geopolitical instability.

Key terms
- Strait of Hormuz
- A critical maritime chokepoint between the Persian Gulf and the Gulf of Oman, through which 20-30% of global oil trade passes. Its strategic importance makes it a focal point in US-Iran tensions, with blockades or disruptions posing severe risks to global energy security.
- A-10 Warthog
- A US ground-attack aircraft renowned for close air support missions. Its extension until 2030 underscores its role in regional conflicts, including strikes against Iranian assets, highlighting the militarization of geopolitical disputes.
- Hezbollah
- A Lebanon-based Shia Islamist political party and militant group backed by Iran. It opposes Israel and US influence in the region, complicating peace efforts and representing Iran's proxy influence in West Asia.
- Naval Blockade
- A maritime strategy to restrict access to a nation's ports, often used as an economic warfare tool. The US blockade of Iran leverages Article 51 of the UN Charter (self-defense), though its proportionality is debated under international law.
