No one said it would be easy. But for a country to deploy even a few hundred people shouldn’t be a challenge.

If a country can’t close a road, how would it hold up during an attack or war?

This should be a well trained, standard procedure.

Canada is in between mainland US and Alaska. US citizens were allowed to drive thru without diversion. Some didn’t follow the rules and made unnecessary detours. They were fined $600,000 for that. You just need a couple of these cases to make the news to deter people from skirting the laws.

Da Nang also had small road leaks at first. Then those who were diverting via those roads were caught and punished. Roads were closed.
