Another half dozen countries are already talking about and I suspect more will follow suit, likely within the next several months I'm sure. Not all will vote right away but wait to see how things progress for the UK and those few that follow. I suspect a few to vote within 6-12 months however.
I've never agreed with the EU nor the UN nor any other foreign entity that believes they should have any say whatsoever in the matters of an individual country. I believe the UK will grow and thrive now that they have cut EU ties though not without some pains in the short term.
Was watching financial analysts this morning and the sensationalizing and fear talk was incredible shameful. Markets will drop which is a known fact, mostly due to automated selling however things will bounce back and typically do. I couldn't believe some networks had "experts" saying people should sell everything and wait until the market settles to reinvest in the markets. I mean wow!
As far as the US goes.. I hope nothing gets written in stone until after our elections. The UN is screaming that the UK needs to pull out right away and as they said "gone is gone". While I agree, don't think for a second that's not a push, at least in part, to have deals made before our elections this fall.
It'll be quite exciting to see how the events unfold of the next couple months and years for sure!
