the EU is the worlds largest trading block & the USAs biggest trading partner with China second.Like China the EU and the USA are interdependent & all said and done Wall St will call the shots.The so called trade wars are just bickering , jockeying for position between frenemies .Covid has shown the reality of global trade and supply lines - the idea that any large country or trading block can just slam the door on another is a non starter.Trump has damaged American hegemony & now that he has delivered the required tax cuts to the oligarchs the kinder , more palatable neoliberalism that Biden offers is the preferred choice.
Fishing is a tiny part of GDP & Johnson's willingness to sabotage the deal only makes sense if he's looking for an excuse for hard Brexit.London is the worlds number 1 centre for money laundering & out of the 29 locations identified bu the IMF as offshore financial centres 18 are British territories or have strong links to the UK .
So it looks like the plan is they haven't got a plan , just a vague idea to double down on the lies that they used to justify Brexit & see which way the wind blows ,exploiting the fear and confusion. If it goes pear shaped there's a future as an offshore tax haven .As for regaining sovereignty for Parliament the close on 60% that didn't vote tory are looking at a government that wants to restrict whats taught in schools according to ideology , give soldiers immunity for war crimes & allow secret agents and police snitches free reign to commit crimes.As in the USA when those who oppose the authoritarian moves of the state become the enemy alarm bells should ring.
