True. And Germany's voice carries some weight. But what you may be unaware of is the amount of people that are sick with Brexit and sick with the UK being a difficult child in all of this. This is purely a political question now. The continent's economies are behind their politicians. Yes, even the German auto industry is actually quite alright with the UK crashing out if it means the EU can move on swiftly. And if it becomes politically opportune to deny the extension, these politicians might just veto it. Do you know anything about the political discussion in Lithuania? I don't. Are you sure there is not one country in the 26 where a politician might not cash in some political capital by being the hardliner in this? Hungary maybe? Poland? I wouldn't presume to know what they're debating in their cabinets. And Belgium has shown us that sometimes even small regions can throw a wrench into the gears to almost stop a giant FTA with Canada...
This is very much a game of chance. And the cards are stacked against you.
If the HoC rejects this deal, which some people say is rather likely, why would it be in the interest of the EU to grant another extension? This is a question British people usually respond with "to not let the UK fall into ruin" or some other nonsense. But they don't get the question. It's the old "The British are the centre of the world" type thinking.
So, you give it a shot... what would the EU get out of an extension. Just us, because this is us deciding. What would you put on the table to make it juicy for us? Because what we got on the table is "moving on and ending this shitshow that's hurting our economies already and is distracting from the actual political topics we ought to address".
