the empire has been after iran since oil was discovered there at the turn of the last century, about 1910. the author of this piece with much more at the link below, will show you some of the lengths it travels to impose its control on others;

The United States government is preparing to implement an additional level of sanctions against Iran for its refusal to meet a dozen demands that are so absurdly unreasonable that they have been called a regime change policy in all but name. The sanctions which have already been implemented have already badly hurt the Iranian economy, the sting of which is being felt first and foremost by Iran’s poor and sickly.
In an article titled “Iran’s poor to bear brunt of Trump’s oil sanctions“, Financial Times documents how poor Iranians are already strained to the breaking point from the cutbacks they’ve had to make in food and groceries. An article titled “In Iran, US sanctions are being felt, with harsher measures to come” by the Christian Science Monitor details difficulties Iranian charities are having getting medicine to sick children, including chemotherapy treatment, having already run out of four life-saving drugs. In an article titled “US fails to shield humanitarian trade with Iran as sanctions loom“, Al Monitor details the way humanitarian aid, while ostensibly exempt from the sanctions, has been severely impacted by their economic aspect because humanitarian aid costs money. The Wall Street Journal further explains the effects of America’s economic warfare on ordinary Iranian civilians in an article titled “Iran Moves to Shelter Millions as U.S. Sanctions Bite“.
This is before the US implements a new level of attacks upon Iran’s oil industry, a primary economic lifeline, which is scheduled to begin on November fifth. If Iran can’t find a way to get around these crushing sanctions in a significant way, many civilians already stretched far too thin will be pushed past the breaking point.
And who is the US government blaming for the consequences of its economic warfare? Why, the Iranian government, of course.
