Will Iran Marry Eurasian Economic Union or BREXIT secret deal?

Iran has been isolated for decades and prevented from joining BRICKS, World Trade Organization, and Middle East has been always unstable for possibility of any Economic and Political Union. Iranian had to wrestle economic warfare while watching China, South Korea, and EU match raw industrial outputs and then advance in industrial and technological outputs. Iran needs an ally that backs it up and form a block that can help it go independence in many aspects or give Iran access to Markets of many different region for Iranian products. Alliance with America feels very hard to make specially since there are armies of microphones promoting action against Iran. There remains two options Russia (Eurasian Economic Union) or Alliance with Canada, Australia, and Britain as post BREXIT global alliance.
