What would happen if people from the United Nations and NGOs entered a country without permission from...?

Question

its dictators? Say, if they flew a helicopter right past the red tape (figurative) and into a disaster-struck area to help with humanitarian relief?

Answer 1

The military of the violated country would have the right to shoot down any aircraft used for such, to arrest any person involved in such -- even to shoot them. To violate the sovereignty of a country is considered an act of war.

The UN and NGOs will NOT go into a country unless they are invited. Respecting a country's sovereignty is absolutely critical/fundamental to their being able to provide aid to people who need it most.

Answer 2

They'd have some 'splainin to do.

Answer 3

They would be in trouble.  The Dic head would seize whatever they brought in and keep it to fulfill their greed.
