What food insecurity? We joined a successful agricultural union (the EEC, in 1973) and remained a member of its successor for decades and had fantastic access to produce, and some of the cheapest food in the EU (also thanks to a highly competitive grocery sector) Even since leaving, the food supply issues have been very minor. We may have food insecurity in the future but I'm confused if you're implying we've had any…
If a country depends on foreign imports just to satisfy basic needs then they are food insecure, by definition. Membership in alliances and trading blocs is temporary, and if other countries have the power to cut you off then that's an existential threat. You would think that the UK would have learned something from the food shortages during WWII when a blockade was in effect. The country might have starved if not fo…
The World Food Programme define it as "Food security exists when people have access to enough safe and nutritious food for normal growth and development, and an active and healthy life". They also link to the IPC (Integrated Food Security Phase Classification), which hasn't even ranked much of Europe, I imagine for quite obvious reasons.
The FAO (Food and Agriculture Organization of the United Nations) defines it as "the generally accepted definition of food security is "a situation in which all people at all times have access to adequate quantities of safe and nutritious food to lead a healthy and active life".
Importing food can strengthen food security. Complete self-sufficiency can be a weakness too - we have one bad year of weather and oops sorry people starve because we did away with our all produce import systems?
Systemic resilience to me seems more important that the exact origin of the food.
We are a country adept at international trade and I don't see why we should stop over some odd notion that imports are bad.
Many, many other countries import a lot of their food. We are not weird outliers.
Which countries do you think we should model ourselves over, out of curiosity? Who excels at self sufficiency (except the US - we aren't all blessed at having the power, geography and climate of the US. Nor frankly do we think their agricultural system is an example to copy)

Regarding WWII, of course the entire continent learnt a lot of hard lessons - particularly about agricultural policy. I already mentioned the EEC. Desire for peace was a big reason for agricultural co-operation, if I recall my history correctly. The continent with many countries that loved wars would have no problem going to war over food
