I understand that point, Al, and I also understand that things like the Berlin wall and - if it happens - the Mexican wall are built by one side. But the actual border is the distinction between two sides, whether trade, nationality, taxation, religion, ethos or whatever. The walls and checkpoints are just a means of strengthening and enforcing the border. Annexation is when one side regards itself as so powerful that it can ignore the border, so once again, the requirement both sides agree on the border to maintain it applies.


Anyway, that's my two pennyworth. Other people are perfectly entitled to their opinion. As usual I will stick to my "state-explain-shut up" approach to threads.
