The essay, titled "Iran Raises the Red Flag of Revenge Over the Jamkaran Mosque as Shiite Muslims All Over the Globe Start to Commit Acts of Terror," is a March 1, 2026, post by Michael Snyder on his Substack. It argues that the U.S.-Israeli strikes killing Iran's Supreme Leader Ayatollah Ali Khamenei and other leaders have unleashed a global wave of Shiite Muslim vengeance, potentially activating sleeper cells for terror attacks in the West. Key points include:

The strikes killed Khamenei, his family members, and 48 top officials, framing it as a catalyst for unprecedented retaliation among ~200 million Shiites worldwide.

Iran raised a symbolic red flag of revenge over the Jamkaran Mosque, signalling a "day of vengeance," with the IRGC promising massive attacks on U.S. and Israeli targets.

Cited incidents: Iranian missiles killing nine in Israel; strikes on U.S. bases causing American casualties; a Texas bar shooting by a suspect with Islamic and possible Iranian symbols; violent protests in Pakistan and Iraq targeting U.S. sites, resulting in deaths.

Warnings of escalating terror in the West, implying 2.5 million U.S. Shiites could include sympathisers or operatives, with the Texas event as an early sign. It predicts unlimited revenge if the conflict prolongs, saying "we are truly in unprecedented territory" and "this is probably just the beginning of the terror."

The piece relies on media reports (e.g., Daily Mail, Times of Israel) but speculates broadly on Shiite motivations.

Based on current reporting and expert analyses as of early March 2026, the risk of terror attacks from Iranian-linked sleeper cells or proxies in the West (e.g., U.S., Europe) is considered elevated but not imminent, with no publicly confirmed active plots, which does not mean much. Intelligence agencies like the FBI and DHS are monitoring suspected cells, particularly those tied to Hezbollah or IRGC, following the Khamenei strikes, so we sure that this will be useless too. Experts warn that Iran, facing an "existential" threat, could activate dormant assets for asymmetric retaliation, including attacks on soft targets like civilians, diplomats, or infrastructure. For instance:

In the U.S., concerns stem from past warnings (e.g., 2025 DHS bulletins) about IRGC-backed cells, amplified by the Austin, Texas shooting (linked to a suspect with alleged Iran ties) and a Canada gym attack on a dissident. No widespread activation has been detected, but vigilance is high amid open borders debates and proxy threats.

In Europe, German lawmakers and officials highlight Iran's history of extraterritorial operations (e.g., past diplomat attacks in Thailand, India), with alerts for possible reprisals via sleeper cells. UK, France, and Germany are on alert, but threats remain speculative.

Overall probability: Analysts like those from the Soufan Center rate it as a "serious threat" if the conflict escalates, but emphasise it's more likely in the Middle East than the West. Social media fears (e.g., X posts warning of U.S. cells) are common.

Dangers in Australia

Australia faces a somewhat higher contextual risk due to prior IRGC-linked incidents, but current threats from Iranian sleeper cells remain low and unconfirmed as of March 4, 2026. The government has taken strong stances against Iran, including expelling its ambassador in 2024 after attacks on Jewish sites (e.g., Melbourne synagogue firebombing), listing the IRGC as a state sponsor of terrorism, and suspending embassy operations in Tehran. Recent developments:

Australia supports the U.S.-Israeli strikes, citing Iran's nuclear and missile threats, but urges de-escalation and legal explanations. This could make it a reprisal target, though no specific post-strike threats have materialised yet.

Travel advisories: Smart Traveller warns of increased global terrorism risks from Middle East fallout, advising against travel there and vigilance at home (e.g., avoid crowds, report suspicious activity). Potential for protests or lone-actor attacks around foreign interests exists.

Iranian-Australian community: ~50,000 strong, with advocates facing harassment; parliamentary reviews ongoing for IRGC listings. Past events like a 2025 Sydney Hanukkah attack (blamed on Iran) heighten concerns.

Likelihood here is tied to Iran's proxy capabilities, but ASIO and police emphasize preparedness without panic. So, once again, be careful and if needing to go to crowed places, have the "head on swivel" mentality.

"The conflict between the United States, Israel and the Islamist regime in Iran could result in terror blowback across Europe, German security officials have warned.

The chairman of the Bundestag's Parliamentary Control Committee (PKGr), which oversees Germany's intelligence services, warned on Sunday in comments reported by Die Welt that "retaliatory measures" by pro-Iranian regime terrorists, including "sleeper cells in Europe", could not be ruled out.

Meanwhile, a spokesman for the Ministry of Interior said, "The Iranian regime has repeatedly demonstrated in the past that it carries out its terror beyond its own borders.

"The federal and state security authorities… are highly vigilant and will adjust appropriate protective measures as needed."

Berlin's Commissioner for Jewish Life and the Fight against Antisemitism, Felix Klein, said that in light of the conflict in Iran, it would be prudent to "assume an increased threat level for Jewish life in Germany."

Following the outbreak of fighting, several German states said that they would review their security measures to protect Jewish or Israeli institutions, many of which have already been on high alert in the wake of the October 7th terror attacks on Israel by Hamas terrorists in 2023

In neighbouring France, Interior Minister Laurent Nuñez called for regional governments to heighten security measures around Jewish places of worship.

"In light of the current international situation in the Middle East, I reiterate my instructions to remain vigilant and ask you to immediately implement enhanced security measures for Jewish places of worship and religious gatherings," he said per Le Figaro.

Over the past decade, France and Germany have been primary targets for Islamic terror attacks in Europe. The two countries have also experienced a significant rise in antisemitic incidents following the October 7th attacks on the Jewish statesTo View Social MediaEnable Social Cookies
