Britain the colonizer of Iran, with help from the CIA, ousted Mohamed Mosadeq the democratically elected Prime Minister of Iran, in 1953 through Operation Ajax, to maintain its control over Iranian oil and natural resources. They re-installed the sha, a brutal, secularist dictator, who tried to Westernize Iran, turning it into a puppet of the West and Israel. The Iranians had enough and got rid of your "Op-Ajax"installed-coup government.
Hezbollah defends Lebanon against Israeli aggression and everyone knows Iran supports them. That doesn't give Israel the right to bomb another nation's embassy. Iran has never directly attacked Israel, while Israel continues to attack Iran within its borders, by assassinating nuclear scientists and whoever else they don't like. The Iranians have every right as a sovereign nation, to generate their electricity from nuclear plants and benefit from that technology. Israel has a nuclear plant and nuclear bombs. Iran has agreed to subject itself to whatever inspections are required by internationally recognized, UN regulatory bodies, for them to be able to develop nuclear electric plants.
Israel continues to murder Iranian scientists and the West does everything to stop Iran from developing its nuclear technology. Iran is a sovereign nation, with every right to benefit from nuclear technology.
I hope this conflict plunges the West into WW3 with Russia and China. That's what American imperialists like you need and deserve, a World War.
