The UK has taken the lead in efforts for EU enlargement. It pushed for the inclusion of Eastern European states. It pushed for Turkey to get its shit together so that it could join (which it made very slow progress with, and has largely been undone by Erdogan)
I was against a EU army but looking into the issue it turns out that it's not a standing army that is being proposed. It's a backstop to NATO should, well, a major contributor be compromised by its biggest threat and suggest that they would not honour their obligations.
a) An isolated #Brexit UK with an EU army on its doorstep?
b) An EU Army where the UK takes a leading role?
There may be a time when a threat to the UK comes at a time when the US chooses not only to not honour its NATO obligations, but actively block NATO from responding.
The UK has resisted joining the Eurozone. It is the global financial capital for € trading - or, at least, it was. It seems likely that will move to somewhere within the EU as the UK loses its financial passporting rights.
After #Brexit, depending how badly and for how long the economy goes tits up, there may be pressure to rejoin the EU.
Rejoining will mean none of the opt-outs we currently enjoy, it will mean adopting the Euro, and being part of Schengen.
Under those conditions, how long will it be until a party runs a General Election under the promise to rejoin the EU?
They *can* see the *near* future, and it is full of costs not worth paying, for benefits that don't exist.
They may not know the far future, but they know that they want the UK to play a leading role in that future, not hide from it.
Reality, not fantasy. Truth, not lies.
