Iran military headquarters vows retaliation, says no decision on Islamabad round-two amid Touska piracy framing

Iran's armed forces headquarters spokesperson Brigadier General Ebrahim Zolfaghari said on state television April 20 that Iran will soon respond and retaliate to the US Navy seizure of M/V Touska in the Gulf of Oman, framing the boarding as armed piracy and theft. The Iranian Foreign Ministry said no decision has been made on participating in the second round of US-Iran talks scheduled to open in Islamabad with VP JD Vance, Steve Witkoff, and Jared Kushner inbound. CNN reported Iran's military closed the Strait of Hormuz again on April 18 after a brief opening. The two-week US-Iran ceasefire expires Wednesday absent extension. Trump told reporters extension is very unlikely unless Iran agrees to a complete uranium-enrichment ban.

Analysis
The divergence between Foreign Ministry caution on the Islamabad track and Zolfaghari's televised retaliation pledge, corroborated across three outlets including direct Iranian state TV citation, is itself the analytical signal: the IRGC line is winning the internal escalation argument, and Iranian retaliation is very likely within 96 hours, most plausibly an IRGC-Aerospace Force anti-ship cruise-missile or limpet-mine strike against a non-US-flagged vessel in the Strait that preserves proxy deniability while imposing visible cost on the blockade. A direct US warship strike is unlikely given ceasefire equities and Trump's Wednesday uranium-enrichment deadline. The April 18 Hormuz closure confirms the IRGC is already executing a pressure campaign, with CyberAv3ngers PLC-linked attacks against US energy or water infrastructure likely as a parallel escalation channel. Tehran may instead forgo kinetic maritime action entirely and route the response through a CyberAv3ngers disruption of a US municipal water utility, imposing domestic political cost on Trump while preserving the Islamabad off-ramp, but the armed-forces factional channel's public commitment makes that pivot increasingly costly to execute.
