I think USA knows it very well. Another thing is what USA clowns say publicly in TV.
USA tried Iran war in January 2012, but Israel and Iran felt llike lacking enough capabilities to start it.
So USA flooded Iran with money in 2015 Iran Deal.
And Israel with advanced weapons like F35.
This is not a tiny USA error.
It's a well planned mayhem in the heart of Eurasian economy by USA, since the Obama administration.
What is happening is likely what USA ruling elite wants: world economy destruction, raw materials and energy consumption decrease.
Of course they can't say this, but if you forget the bullshit they constantly say and just observe USA actions towards Iran since 2010, it's what facts say, destruction of world economy is the main target.
