Yes, it's time for getting closer to Europe again.
I'm no economist, but when Europe is feeling threatened, US global influence has imploded & most countries are struggling to maintain central ground in their governments, it might be an excellent time to begin mentioning rejoining - not to commit to it as set in stone, but I think France, Portugal & spain, Holland & Denmark would all welcome the idea of UK rejoining at the moment, for the same sort of reasons that we would welcome closer ties.
