How is that arrogance?
I would say the same about Germany if we were alone.
GB makes up 3,4% of the worlds GDP. It lost most of it's industry in the past decades. Why would any country not currently having a trade deal with something like the EU, making up 20% of said GDP, or the marginally smaller or bigger blocs China and US, be interested in a trade deal with the UK?
Why would they bring forward a trade deal with the UK before trying to install a free trade area in their very vicinity first? Because, I hate to break it with you, but your trade with countries like India isn't that big to start with and it's rather nonexistent with most other Asian countries.
So, again, tell me: why would that happen?
