That goes far beyond what’s permissible in international law in response to an attack.
In my view the US and Israeli attacks on Iran were illegal, reprehensible, and deeply stupid. But that doesn’t mean Iran is allowed to do whatever it wants afterward, especially to countries not directly involved in hostilities. In this case Iran has also broken international law.
However it should have been dealt with earlier rather than latent bombing.
Anyway, I live in the UK, and I don't swallow the same propaganda as you.
Do you know any actual Iranians? I do!
