Eli5: How exactly do countries keep national and international borders in check?

Question

Especially how does the US mainly, possibly somewhere else, keep borders that are literal boxes, like Wyoming. Or the straight line that is the Canada-Alaska border. Or like the northern African borders, which some of simply seem to run through a random place in the desert. Especially the Newfoundland and Quebec border, it doesn’t look like it follows anything and just goes in random directions.

Answer 1

Respect for law sustains all borders. Where respect for the law fails, either force defends the border, or it eventually moves elsewhere.
