Oh, it's clear? Why did nobody tell me. I take it back then. I am glad to hear a complex evolving geopolitical situation can be easily reducted to a simple judgement like that. It's a relief.
It's clear it's going badly now yes. That's obvious. What you're confusing is the situation now with the situation in the future. I wish I could say it's an easy mistake to make, but it's not. Maybe you can plausibly argue that Brexit will be a success one day in the future, but you absolutely cannot argue that it's a success right now. That would not be serious.
