Iranian Foreign Minister Abbas Araghchi warned that any military action by the U.S. in the escalating war with Israel would be "very, very dangerous for everybody."

Donald Trump is currently considering whether to join Israel in bombing Iran – a seismic decision which could cause chaos across the Middle East and beyond. The UK is particularly nervous to see what the mercurial president does next, knowing that there may well be pressure for Britain to assist America, as one of its closest allies.

Israel's attack on Iran began as a campaign against its nuclear program but has already begun to morph into something far riskier: regime change. It is staking its strategy on deep US involvement, but fault lines between the two are already visible.
