I hope this doesn't mean you're coming home?Bless right back at ya.
We're not looking for ALL of it. Even a tiny fraction of London's financial business migrating to Ireland is a big win for a country the size of Ireland. Anything extra from what is already known is just gravy. And we are getting a fraction of it. We've already won that front.
Post-Brexit we'll be the only English-speaking, politically-stable, well-educated country that is firmly within the EU. That is going to make Ireland an attractive destination for global FDI.
A UI, which is now inevitable and imminent, is a major strategic win for the nation of course, no matter how much poo-pooing might go on from the usual suspects on p.ie.
There are other less tangible wins that we've already banked. Out soft diplomacy profile has been greatly enhanced - worldwide. Our politicians have looked sane, sensible and competent compared to the barking mad lunacy from the Brits. Our political system has mostly reacted to Brexit with a remarkable show of maturity and cross-party unity of purpose. We've demonstrated planning and an ability to react to adverse circumstances out of our control. All these things get noticed.
It has had a subtle but profound cultural/psychological impact on most of the nation. You could even say, without being accused of too much hyperbole, that Brexit is the moment where the Irish grew up and finally graduated onto the world stage in their own right. The long shadow of UK rule and domination has been firmly cast off and it is wonderful to see.
In the long run Brexit is going to be rather awesome for Ireland on all sorts of different levels. Go Brexit!
