Last Friday was the date set for Britain’s withdrawal from the European Union. What might ultimately have happened on this day has been salivated over by some and agonized over by others ever since the UK voted nearly three years ago to withdraw, an event quickly dubbed “Brexit”—Britain Exiting the EU. After the Brexit referendum, British Prime Minister Theresa May had over two years to negotiate an exit strategy that would gain Parliament's support. This proved more difficult than most anticipated, and the deadline was pushed back to April 12, 2019. But with the next deadline looming and nothing concrete in the works, the PM Theresa May and EU leaders agreed to extend this date for another six months; so, for now, the UK remains in the EU. But those not living in the UK may be wondering, why all the angst? Why can’t the UK just withdraw? The short answer is, they could. The long answer is much, much more complicated.
