How is the US-Israeli war on Iran causing havoc in Europe?

Several Western European nations have expressed their opposition to the potential resumption of the Iran war, as spiralling global oil prices have worsened the cost of living crisis across Europe. Countries such as Germany and the UK, among other major powers, which initially remained silent on the US-Israeli bombardment of Iran, have aired their views, calling for diplomacy to end the war which has disrupted global oil supplies. Continued disruption to energy supplies is pushing up household costs as winter in Europe approaches, adding fuel to protests over living standards that have engulfed European capitals in recent weeks.
