In my opinion, an alliance between Russia, Iran, China, India, Vietnam, etc. will define the future. Iran is the ancient civilization. Many concepts and inventions, which we use daily nowadays, were created by the human genius in the ancient Persia.
In comparison, the EU project, or even the US project, have got a serious weakness, - littleness. Eurasia has got 54 million square kilometers of territory, 5 billion population https://en.wikipedia.org/wiki/...
Firstly a modern railway network connecting the whole Eurasia, Americas, Africa should be built. Thousands of tunnels, bridges, etc. It will be the work for millions. But for this there should be a leadership in the world. The problem with current leadership is again - the littleness.
I think it is a good idea to cooperate with Iran in space and in other domains.
