WTF is wrong with you? Seriously the myopia, if not sheer bloody minded blindness on display is incredible. WTF do you think is going happen when the UK has no trade deals in place, no agreements for their citizens abroad, no agreements for all the migrant workers currently resident in the UK, no agreements on the border between Northern Ireland and Ireland, no plan or money to replace all the countless subsidies UK educational institutions and farmers currently receive etc etc etc.
I just can't believe a person who doesn't need a voice saying 'breath in, breath out' to remind them how to stay alive can be this blindly farking stupid.
Trade deals take years to negotiate, Britain is not the world superpower any more, they aren't sitting offshore tiny nations in force saying 'trade or else' anymore. No-one has to trade with them at the end of a gun anymore, which is I assume what you are hankering back to when you want to make Britain Great Again - the empire, tallyho old chaps and the sun doesn't go down on etc.
Ireland will collapse back into the violence.
Scotland will leave the union.
Farmers will go bankrupt without the cheap labour and subsidies propping them up.
In short leaving the EU is a monumental F-UP of Biblical proportions.
