The reason the EU is making things awkward for us is threefold:
1. Dictatorships like building bigger & bigger empires as it gives them more power and riches to indulge themselves on. If we make a success of Brexit with much higher economic growth (not difficult with their poor record),then other countries will start asking the question, why shouldn't we.
2. We can trade very happily on WTO terms like most of the rest of the world including with the EU. When there are a range of rules (rarer and rarer these days as there are several standards organisations which create standards which are universally adopted including by the EU). However, there are some problematic areas where we have transferred our standards sovereignty to the EU and signed up to their gold plated versions. A transition period of up to two years should resolve this so we can rejoin the standards bodies and get other alternative arrangements in place.
3. Under WTO rules they are not allowed to discriminate against us but we all know what EU commission & French bloody mindness can do while we take them to WTO arbitration, where the WTO can fine them.
Finally this food shortage tosh is exactly that. Anybody that gets a calculator out can see that. Global population in 2018 is 7,600m. UK population is 65m less than 1%. We produce about 40% of our own food, plus on top of this much of our food comes from the rest of the world like winter fruit from the southern hemisphere as there seasons are the opposite of ours. If the EU banned all food to the UK we would increase world demand by less than 0.5%. UK food buyers are used to dealing globally with suppliers and also commodity markets which for many staple basics like wheat, rice, sugar, vegetable oils are priced in USD with the US controlling the commodity traders.
If the EU want a trade war our 50bn trade deficit will disappear very quickly plus much more. The French, Germans, Spanish, Dutch and Danish farmers will not like the drop in income from losing our food market at the same time as EU budgets are squeezed from losing our contribution. Do you really want to ruled by a dictatorship that is making these kinds of threats against us?
This EU food trade situation is exactly what has happened in the US with Trump pulling out of TIPP and now with retalitarity sanctions on US food. The US government are subsidizing US farmers to make up there shortfall. Trump pulling out of TIPP has increased Australasian mutual trading where they are buying from each other lower tariff cheaper substituted US products. It has also been good for the UK meat trade where our meat is seen as premium produce with sales going up in countries like Japan.
All this daily Remoaner project fear, fake news, propaganda is getting increasingly boring where I just take it for the total bullsh*t it is.
