When you get technical about this 100 miles from every international airport is a border as well...

How does that impact that map ?

There is no actual country border at any airport. It's an approximation that has its own rules and is not affected by the international treaty that sets these 100 miles.

The 100 miles have nothing to do with international treaty, but only American courts' interpretation of the fourth amendment.

Isn't that based on the treaty? Sorry if I'm mistaken.

I'm not sure which treaty you're thinking of, but I'm pretty certain it's a purely domestic matter. Note that we're talking about 100 miles inland from the border, not something like 100 miles out to sea.

Yeah, that's my mistake. I thought we're talking out, not in.
