Answer

This sounds like the terminology surrounding Brexit. In the case of the UK and Ireland, the backstop is, in short, a way to avoid building a physical border, with checkpoints for goods, on the boundary between Ireland, a European Union member country, and Northern Ireland, a part of the United Kingdom.
