This is where the Brexiters' "regaining of sovereignty from the EU" leads us - IRAN Relations

To the brink of provoking a war in the interest of the US, even when it was them that tore up the nuclear treaty holding peace together in the powder-keg Middle East.

This story actually began on 18 May 2018, when Donald Trump unilaterally withdrew the US from the 2015 nuclear accord with Iran. Tehran initially continued to apply the restrictions imposed on them by the treaty and enjoyed the support of much of the rest of the world, including the deal’s other signatories: the UK, Germany, France, Russia and China.

Since then Trump has applied increasingly swingeing extraterratorial sanctions on trade with Iran and has been brow-beating foreign governments to comply with the US. And Iran has become increasingly active in disrupting and threatening shipping in the Gulf of Hormuz.

The level-headed analysis comes from one of our friends in the EU and... Jeremy Corbyn who is quoted as saying "Escalation risks a slide into an even deeper conflict. President Trump’s decision to tear up the Iran nuclear deal fuelled the risk of full-scale conflict. A negotiated reinstatement of the nuclear deal through the UN is essential to wind down tensions and defuse the threat of war in the Gulf.”

The Guardian article reports that:
"Carl Bildt, the former Swedish prime minister and co-chair of the European council on foreign relations, pinpointed the ambiguities of the British action in Gibraltar: “The legality of the UK seizure of a tanker heading for Syria with oil from Iran intrigues me. One refers to EU sanctions against Syria, but Iran is not a member of the EU. And the EU as a principle doesn’t impose its sanctions on others. That’s what the US does.”

To the Iranian eye, the British action had nothing to do with an EU embargo, and everything to do with an desire to support the US squeeze on Iranian oil exports, the quickest route to bringing the Iranian economy to its knees. Some reports estimate that Iranian exports are down to 200,000 barrels a month."

Unlike the UK, which wants to jettison half of its trade deals and risk the rest, Iran is concerned with protecting theirs, even in the face of US provocation and the EU embargo on oil to Iran in effect since 2012.
