Iran killed an American contractor. We sent an airstrike to the militia who killed the contractor. The militia then attacker our embassy in Baghdad. We then sent an airstrike to the leader of the Iranian military. Both countries have said severe threats to each other with implied war.
Realistically, could Iran and the US go to war, and could WW3 start? The US literally killed a high ranking leader of a country, which is how WW1 started (the assassination of Franz Ferdinand), and, as the UK has the same view on Iran as the US, and the US has lots of NATO allies, whereas Iran is backed by Russia and China, could other world powers be brought in, sparking WW3?
