Sorry that I have to say this, but that's very simplistic.

If two parties agree on any contract or trade agreement, the parties are not always of equal weight and do have their own interests at heart. The UK needs the EU more than the other way around, so the EU has more pull and will make use of it. So "bully your client states into submission" is not a fair description to use, to put it politely. You could say that about any deal where one party has an advantage.
