The stability of any country you rely on for power is indeed a major concern.

Alas during the previous Trump presidency, Europe saw that modern Republican 'America First' thinking doesn't just call for a wall with Mexico, a travel ban with Muslim countries, and a trade war with China - it also wants a trade war with Europe.

And linking the south of Spain to the north of Morocco only needs ~200km of undersea cable, rather than the ~6000km an EU-to-US link would call for. That's a pretty big benefit.
