Yeah, it does seem pretty inevitable now.
However, let's hold on: we could get some luck. There's 4 years for Starmer or Farage to fuck up politically or suffer some physically debilitating condition which might give us a way out of that. Or a charismatic star might arise in the Corbyn-Sultana party who will dominate UK politics (I can dream

), despite this making us reliant on the whims of Trump and any future POTUS who could therefore shut down our air force. Brilliant strategic work from the Grima Wormtongue of the world stage.
