The entire process of Brexit will seem a little odd to most Americans. You had an all-out and bloody war last time some people decided to secede from the United States. We in the United Kingdom just had a vote and a few arguments about the details of how we will leave the European Union.

One of which is mystifying even to most Europeans, the arguments over the border between Northern Ireland and the Republic of Ireland. The latter will remain part of the EU (although, to be honest, possibly not for all that long) while the former will leave along with the rest of the U.K. The problem here is that this will be the only land border between those newly outside the EU and those still inside the EU.
