1988 fight between U.S. forces and Iran after a U.S. frigate hit a mine

About

Operation Praying Mantis was the 18 April 1988 attack by the United States on Iranian naval targets in the Persian Gulf in retaliation for the mining of a U.S. warship four days earlier. It took place during the US presidency of Ronald Reagan and the rule of Supreme Leader of Iran Ruhollah Khomeini.

after a U.S. frigate hit a mine. The 2015 Joint Comprehensive Plan of Action temporarily constrained Iran's nuclear programme before the United States withdrew in 2018. In 2019, tanker attacks and ship seizures again raised fears of a Hormuz crisis. The International Energy Agency's March 2026 report said the latest conflict created the largest supply disruption in global oil-market history.

The wider picture

The deal tests whether energy chokepoints can be stabilised through a transactional ceasefire while deeper strategic disputes remain unresolved. Iran gains relief from immediate blockade and sanctions pressure; Washington gains a path to reopen shipping and restart nuclear talks. Gulf states, Europe and Asian importers gain breathing room, but only if Hormuz is treated as reliably open by shipowners and insurers.

Why now

The story is timely because Pakistan's prime minister said on 17 June 2026 that the signed memorandum had immediate effect, and markets reacted on 18 June with lower oil prices and higher Asian equities. The trigger is the signature, not merely another round of talks.

Context & what happens next

What to watch

Watch whether the planned Switzerland contacts proceed, whether Iran and the United States publish or clarify the memorandum text, whether tanker traffic and insurance rates normalise, and whether IAEA-linked uranium steps are specified inside the 60-day negotiating period described by U.S. officials.

What to do

Belgian readers should not expect pump prices or air fares to reset overnight: fuel contracts, taxes, stocks and retailer pricing slow the pass-through from crude markets. The practical signal is direction. If Brent and shipping-risk costs keep easing, pressure on transport-heavy bills should soften; if the deal frays, volatility can return quickly.

Voices & reactions

What the main actors are doing

Reported positions, summarised — not direct quotations

Energy-market analysts

AP quotes Rice University's Baker Institute energy researcher Jim Krane as arguing that reopening Hormuz helps a tight market immediately, because oil stocks are low and any extra Iranian or Gulf supply relieves pressure. This view treats the framework first as an energy-security stabiliser, while warning that a later oversupply cycle is possible if production elsewhere has already ramped up.

U.S. Republican Iran hawks

AP quotes Senators Bill Cassidy and Ted Cruz as arguing that the framework rewards coercion by easing sanctions while leaving Iran with future leverage over Hormuz tolls and unresolved nuclear questions. Their strongest case is that short-term price relief may come at the cost of normalising Iranian control over a global maritime chokepoint.

G7-aligned de-escalation camp

Axios reports that Emmanuel Macron said the signature could reopen Hormuz and support lasting peace. This camp's strongest argument is that a flawed interim framework is preferable to an open-ended war that keeps energy markets, Lebanon, Gulf shipping and nuclear diplomacy in crisis at the same time.
