How is the UK no longer reliable? Even the US is probably reliable for Nato defence outside of Cyber where war looks more like espionage. The world does need the EU to step up it's leadership, but we're not at a breaking point yet. I also think that a coalition of France, Canada, and the UK could act as a decision making block in light of the political situation in America right now. The UK is still one of the most powerful atomic weapons armed countries and has good relations with many countries around the world, France is the most powerful / stable EU country with good relations with many countries around the world, and Canada could act as a good representative for North America and has enough soft power and reputation to pull together non-aligned countries and other members of the global liberal order.
