Iran has issued a stark warning to regional countries that any backing for the United States in the event of a renewed armed conflict will be treated as a hostile act toward Tehran, an Iranian parliamentary official said on Friday, 23 October 2026. The warning signals a sharp escalation in Iran's diplomatic posture as the possibility of further US military action remains publicly on the table.

Iran's Warning to Regional States

Fada Hossein Maleki, a member of the Iranian parliament's National Security and Foreign Policy Committee, said Tehran would be capable of identifying which regional states are prepared to support American forces if military action resumes. 'In that case, the decisions taken by Iran may go beyond strikes on the military bases of those countries, and those countries themselves will be classified as hostile states,' Maleki said in an interview.

The statement is notable in its breadth — it does not name specific countries but implicitly targets Gulf states and others in the region that host US military installations. This is not the first time Iran has made such warnings, but the explicit mention of military retaliation beyond base strikes raises the stakes considerably.

Iran's Foreign Minister Targets US-Israel Defence Ties

Iranian Foreign Minister Seyed Abbas Araghchi separately alleged on Friday that the United States has spent $11 billion in taxpayer funds on missile defence for Israel over the past three years, according to reports. 'It has fired more interceptors defending Israel than Israel has,' Araghchi reportedly said. 'That is not a symbiotic relationship. It is a parasitic one.'

The remarks reflect Tehran's broader narrative that Washington's military involvement in the region is primarily driven by its commitment to Israeli security rather than US national interest — a framing aimed at fracturing domestic American consensus on the conflict.

Trump Signals Further Military Action May Be Possible

US President Donald Trump, speaking to reporters before departing Washington, suggested that further military action against Iran remained a possibility, while acknowledging that the conflict carries a political cost for Republicans ahead of approaching congressional elections. 'The Iran War, and we've knocked the hell out of them, and we may do it a little bit further,' Trump said.

When asked how the conflict had affected the election campaign, Trump indicated that public opinion was divided. 'Well in one way, they love it because I'm doing what should have been done by other presidents, and another way maybe they don't,' he told reporters. 'It's — there's a price to pay, which I knew immediately when I did it, but we can't let Iran have a nuclear weapon.'

Trump did not specify whether a new operation was being planned, identify any potential targets, or provide a timetable for further action.

Implications for the Region

Iran's warning puts several US-aligned regional governments in a difficult position. Countries hosting American bases — including those across the Gulf — now face an explicit Iranian threat of classification as hostile states if they are seen cooperating with US forces. This comes amid an already volatile regional environment, with the conflict having reshaped security calculations from the Levant to the Persian Gulf.

Analysts note that Iran's messaging is calibrated: firm enough to deter regional cooperation with Washington, yet short of a direct military ultimatum that could trigger an immediate escalation. Whether that balance holds will likely depend on Washington's next move.
