@david you are wrong, you will disagree if course and I fully expect you to, but Iran’s expansionist tendencies are limited to groups in other countries fighting against Israel/the US. Iran is on its knees economically so any expansionist ideas they have, and like all regimes they probably have them , are impossible. Also the Iranian regime fears western allies being drawn into a war because its own population would rise up to get rid of the regime knowing western allies could help them. And Afghanistan is a mess, it can’t manage its own affairs let alone imagine expanding its ideology elsewhere.
The only country with expansionist tendencies in the region is Israel, intent upon expanding into Northern Gaza and Southern Lebanon.
The thing is the way you and most Israelis view this war is not the way the majority of people around the world view it. They see Israel - with its first world status, billions in the way of funds and state of the art weaponry, and a hardline leader/government - as the real aggressor in all of this and the only nation with expansionist tendencies being played out in real time.
Nobody disputes that Israel needs to defend its people, but with a dome of iron and an army that is the largest and best armed in the region as well as nukes I worry more about those it is pounding into the dust who have no defences.
