My brain has been working overtime, and I thought this chain of events might have caused UK to vote Brexit:
Sept 11 terror attacks in US;
Invasion of Afghanistan and then Iraq, as a result (war on terror);
Susequent withdrawal of troops from Iraq, causing a vacuum;
Rise of ISIS as a result of the vacuum;
This causes displacement of Middle Eastern people, many of whom go to Europe;
This causes uprising of right wing support in many countries, including the UK;
UK conservative party promise a referendum if they win the 2015 election (to stave of growing support for UK Independence Party);
They win election, and referendum is called.
What do you think???
