Not to be rude, but your Government, MOD, and think-tanks disagree with you. The latent capacity of UK agriculture is estimated to be able to feed approximately 80-90% of the population, which for context is similar to the amount of food available (including external aid) in South Sudan now.
> And let's not pretend NI is included under any sensible scenario other than the British military blockading and subsuming control of RoI. There's no scenario where a blockade of Britain as an island would leave us "struggling to feed NI with RoI being supported by the European block" as another absolutist.
The UK does not have the ability to militarily conquer Ireland, let alone survive the consequences, so this is, well, delusional.
I honestly do not think you are well informed enough to form a valid opinion on this topic, which explains your reactive and emotion-driven comments
