The support Randolph Churchill and his son, Winston, showed for Israel's victory in the Six-Day War can't be found today in the "Islamic Republic of Britain," Prime Minister Benjamin Netanyahu said during an interview over the weekend with Israel's Army Radio.

“Incidentally, he [younger Winston Churchill] and his father, Randolph, Churchill’s son, came here and covered the Six-Day War in a way that was very favorable toward us,” Netanyahu said. “Try finding that in Britain today, in what is called the Islamic Republic of Britain.”

Netanyahu also recalled a phrase someone had said that "the first Islamic republic with nuclear weapons will be the Islamic Republic of Britain."

"We’re making sure there won’t be another one, you know, in Iran," he stated.

Notably, the Islamic Republic of Pakistan has had an active nuclear program since 1972.

Khamenei posters, Iran regime flags displayed at London march

Tensions between Israel and the Britain have grown strained over the past few months, and even more so since British Prime Minister Andy Burnham took over from Keir Starmer.

Last week, open displays of support for the Islamic Regime in Iran were seen throughout Sunday’s Arbaeen Procession in London.

The Arbaeen Procession is an annual public march held to commemorate Imam Hussain ibn Ali, the grandson of Prophet Muhammad, who was martyred in Karbala, Iraq, in 680 CE.

The Jerusalem Post reviewed hundreds of videos and photos from the event, finding at least dozens of posters and flags of former supreme leader Ayatollah Ali Khamenei, as well as hundreds of Islamic regime flags.

One in particular stood out: a poster by the Islamic Human Rights Commission with the words “Choose the right side of history” superimposed on a photo of Khamenei.

The IHRC has been investigated by the UK’s Charity Commission since 2017 for its alleged ties to the Iranian regime.

Also visible in the footage from Sunday was a man wearing a keffiyeh featuring the three supreme leaders of the Islamic regime: erstwhile supreme leader Ruhollah Khomeini, Ali Khamenei, and Supreme Leader Mojtaba Khamenei.

The brazen displays of pro-regime propaganda during Sunday’s Arbaeen march were particularly striking given the UK’s recent introduction of the National Security (State Threats) Act 2026.
