US Warns It Can Resume War with Iran as Deal Remains Elusive

The United States has signaled it retains the military option to resume hostilities with Iran after diplomatic efforts to revive the 2015 nuclear deal collapsed, with officials warning Tehran that “all options remain on the table.” The escalation comes as the Biden administration faces pressure from hardliners—including figures like former Trump aide Pete Hegseth—who argue for a more aggressive stance. Meanwhile, Iran’s Supreme Leader Ali Khamenei has dismissed U.S. Demands for concessions, deepening a stalemate that threatens to disrupt global oil markets, regional security, and sanctions architecture. Here’s why this matters: a war between the two nations would trigger a humanitarian crisis in the Gulf, destabilize the EU’s energy security, and force China to choose between its economic ties with Tehran and its strategic alliance with Washington.

The Chessboard Shifts: How This Moves the Global Power Triangle

This isn’t just about Iran and the U.S.—it’s about a three-way tug-of-war between Washington, Beijing, and Moscow. China, Iran’s largest trade partner, has quietly ramped up oil imports from Tehran since U.S. Sanctions were reimposed in 2018, now accounting for over 1 million barrels per day, despite U.S. Threats of secondary sanctions. Here’s the catch: China’s reluctance to fully align with Iran reflects its fear of provoking Washington, which could trigger a broader economic war. Russia, meanwhile, sees Iran as a critical partner in its arms trade, with Tehran supplying drones to Moscow’s war in Ukraine—a relationship that has already drawn U.S. Retaliation, including strikes on Iranian-backed militias in Syria.

But the real leverage lies with Europe. The EU’s 2023 Joint Comprehensive Plan of Action (JCPOA) revival efforts have stalled, leaving Brussels vulnerable to energy shocks. Iran’s oil exports to Europe have dropped by 40% since 2022, forcing the bloc to rely more heavily on U.S. LNG and Middle Eastern suppliers like Qatar. The irony? Europe’s green transition has made it more dependent on U.S. Fracked gas—precisely the energy source Washington has long opposed.

“The U.S. Is playing a dangerous game of brinkmanship. If they strike Iran, they risk a regional conflagration that could draw in Hezbollah, the Houthis, and even Russia. The question is: Does Washington have a Plan B beyond kinetic strikes?”

— Dr. Trita Parsi, Executive Vice President of the Quincy Institute for Responsible Statecraft

Supply Chains on the Brink: The Hidden Costs of a Gulf War

Let’s talk about the $1.2 trillion in annual trade that flows through the Strait of Hormuz. 30% of the world’s seaborne oil passes through this choke point, and a conflict would send prices soaring—reversing the progress made since the Ukraine war. The IMF has warned that a 20% spike in oil prices would trigger inflation in emerging markets, particularly in India and Indonesia, where fuel subsidies are already strained. For context, the 2022 Russia-Ukraine war caused a 50% surge in diesel prices; a Gulf conflict could double that.

Here’s the domino effect:

  • Shipping: The Red Sea’s Houthi attacks have already forced rerouting of 15% of global container traffic around Africa, adding $5 billion in annual costs. A full-blown Iran-U.S. War would make the Suez Canal impassable.
  • Sanctions: The U.S. Already enforces secondary sanctions on entities trading with Iran. A war would expand these to include China’s tech sector, given its reliance on Iranian semiconductors for drones.
  • Currency Markets: The Iranian rial has lost 80% of its value since 2018. A conflict would trigger capital flight, deepening hyperinflation in a country where 40% of the population already lives below the poverty line.

The Pentagon’s Red Line: What “All Options” Really Means

When U.S. Defense Secretary Lloyd Austin warns that “strikes are back on the table,” he’s referencing three potential scenarios:

US-Iran War: Trump Warns to “Unleash Hell” If Iran Refuses Deal | WION
  1. Limited Airstrikes: Targeted strikes on Iranian nuclear facilities or Revolutionary Guard bases, modeled after the 2020 Baghdad strike that killed Qasem Soleimani. The risk? Iran’s asymmetrical response—attacks on U.S. Bases in Iraq, cyber warfare, or proxy strikes via Hezbollah.
  2. Cyber & Economic Warfare: Disrupting Iran’s oil exports via digital attacks on its National Iranian Oil Company (NIOC) systems, as seen in the Stuxnet attack. This could trigger a $100+ per barrel oil shock within weeks.
  3. Full-Scale Conflict: A ground invasion is unlikely, but a prolonged air campaign could draw in regional allies like Israel and Saudi Arabia. The last time the U.S. And Iran fought directly was in 1988, when the USS Vincennes shot down an Iranian airliner, killing 290 civilians. The fallout? A 20-year diplomatic freeze.

But there’s a wild card: Israel. Jerusalem has conducted hundreds of strikes in Syria and Iraq against Iranian-backed militias since 2020. If the U.S. Escalates, Israel may preemptively strike Iran’s nuclear sites, fearing a U.S. Retreat from the region. This could drag the EU into a sanctions war with Tehran, as Brussels has already begun negotiating a separate trade deal with Iran.

“The U.S. Thinks it can contain this conflict, but history shows that once you start bombing Iran, you can’t stop the regional fire. The Houthis, Hezbollah, and even Pakistan’s ISI will get involved. This isn’t 2003—Iran is not Iraq.”

— Ambassador Ali Vaez, International Crisis Group’s Iran Project Director

The Timeline That Could Change Everything

Date Event Global Impact
2015 JCPOA Signed (Iran Nuclear Deal) Global sanctions lifted; Iran’s oil exports rebound to 2.8 million barrels/day.
2018 U.S. Withdraws from JCPOA Oil prices spike 25%; Iran’s economy contracts 9%.
2020 U.S. Assassinates Qasem Soleimani Iran retaliates with missile strikes on U.S. Bases; 100,000+ Iraqi protesters demand U.S. Withdrawal.
2022 Russia Invades Ukraine Iran supplies Russia with 400+ drones; EU sanctions Iran’s oil sector.
2024 China-Iran 25-Year Cooperation Agreement China pledges $400 billion in investments; U.S. Labels it a “threat to regional stability.”
2026 (May) U.S. Warns of Resumed War Oil futures jump 8% in 48 hours; EU debates energy security strategy.

The Domino Effect: Who Wins and Who Loses?

If diplomacy fails, the winners are clear:

The losers? Everyone else. The EU’s green transition would stall, India’s economy would face fuel shortages, and global food prices would surge as shipping costs skyrocket. Even the U.S. Would suffer: Its military is stretched thin in Ukraine, Taiwan, and now the Gulf.

The Bottom Line: What’s Next?

Here’s the hard truth: This isn’t about Iran’s nuclear program anymore. It’s about who controls the global energy order. The U.S. Is betting that economic pressure—through sanctions and cyber warfare—can force Iran back to the table. Iran is betting that China and Russia will shield it from collapse. And the rest of the world is betting that someone will blink first.

But the real question is this: Does the U.S. Have a Plan B? The last time America went to war in the Middle East without a clear exit strategy, it cost $2 trillion and 7,000 lives. This time, the stakes are higher. The Gulf isn’t Iraq in 2003—it’s a powder keg of proxies, sanctions, and economic warfare. And the world isn’t waiting.

So tell me: If you were in the White House, what would you do differently? Drop your thoughts in the comments—or better yet, write to our geopolitical desk. The clock is ticking.
