The cynic might point out that (geopolitically) Europe has no other choice but to go abroad as equals. Europe has been eclipsed by its former American colony in the West and the Middle Kingdom's re-ascendancy eclipses Europe to the East.
Where does that leave Europe? Once the global engine of growth for ideas, innovation, trade, you name it... Europe nowadays is looking a tad stale.
Economics: Europe needs to close down tax havens within European borders and sphere of influence. Needs to negotiate a fiscal transfer framework to save the € and work to make the € more of a global reserve currency, that means fixing the € project so that the UK gives up the £. Implement a variant of the Tobin tax.
Science: Europe needs to bulk up ESA and promote a private space industry. Needs to double down on projects like CERN and ITER. Needs to get Galileo up and running. Needs to invest more in nuclear and renewable power, wean itself off coal.
Politics: Needs to re-make the UN security council. Needs to work harder towards sorting out Israel/Palestine. Needs to disengage from NATO. The accession of Turkey to the EU needs to happen soon.
Welfare: Needs to move Europe as a whole towards the Scandanavian model which has shown itself to be fairer, more progressive, and more forward thinking. Perhaps needs to experiment with basic income because tech automation seems to be replacing jobs faster than they are being created.
