You want to outsource an incredibly ambitious space program to another country? That'll never happen and I don't know if it should either. Parts of it can be outsourced for sure, but that's it. Like Europe taking over parts of some space projects. Russia being paid for deliveries.
That is insane. Take a USA tax funded public entity and spend the budget of it's most ambitious project in Israel or India. What are you talking about? And we already send money to Russia for Soyuz to get to ISS via ULA.
