Irexit refers to Irish restoration of sovereignty i.e., an Irish movement to leave the European Community.
It provides a good model for other sovereignty movements, including that of Native Americans.
Brexit, the British exit, has recently been sort of finalized, but there is still a lot of behind the scenes trickery by those who want to 'belong' to a larger and more powerful union.

Trends toward local sovereignty are increasing around the world.
Although it seems like common sense that no group should control another group, the ambition to control other people is common all around the world.
Britain had political possession of India until the middle of the 20th century. India seemed on very solid ground in demanding sovereignty. But today Indian nationalism is motivating millions of Indians to see Kashmir as 'theirs', as a necessary part of India.
Of course when Kashmir gets 'independence' there will be sub groups there who want sovereignty. It's a mirror of any differentiation process, including human individuation.

The two opposing sides of any major political issue will use different strategies, and a person should look for the more clever ones.
The Treaty of Lisbon weakened the power of EU members with lower populations in some ways.

Notice that it popped up as an issue just as the major global slowdown of 2008 was starting, and was strengthened by the weakening global economy.
Ireland has a very successful economy. In fact by any measure one of the most successful economies in the world.

Brexit, the British exit from the European Union, is being finalized as the global economy starts what looks like a dramatic slow down. In other words Northern Ireland will be more 'a part of Britain' than 'a part of Europe' politically during the next recession or severe economic troubles.
The two factions in Northern Ireland, pro and anti British, will likely become more polarized as the economy slows, and the Republic of Ireland, which has an education based society, will see reunification as a good defensive economic move, even if that is not yet evident.

All of this is developing as Trump has pushed seemingly irrational policies with regard to China, policies whose net effect will be to encourage independent economies, rather than growing interdependence. Self reliance among nations rather than internationally managed economies.
The economy of course is sensitive to many things, including the actions of policymakers. Just as the Lisbon treaty coincidentally coincided with the 2008 slowdown, the next slowdown is likely to coincide with new nationalist events. Those with the most ability to influence economic events certainly realize the political power their influence holds, and certainly have opinions and preferences with regard to political outcomes.

Not much seems to change over generations of anti colonialist, or pro sovereignty, movements, but there is one variable that has changed and may be behind Trump's actions.
In centuries past, colonization was militarily very easy. Anywhere in the world a thousand men with rifles could easily control a hundred thousand without.
Today though the balance has flipped. Whether in Ireland or North America or China or Brazil, it is now the solitary activist or small group of activists which have military power.
An army of a thousand men with rifles cannot easily control a hundred thousand people who have weapons much more dangerous than rifles.
In some places melting potters see surveillance and other police controls as the solution. China has created a massive surveillance and monitoring system to keep its conquered groups in line, a massive mix of pro state technology and propaganda that almost rivals that of the United States.
