What problems do you think a stateless nation faces that nation-states do not?

A stateless nation can face several disadvantages compared to a nation-state. First, all they are not represented in a worldwide organization like UN that protects nations sovereignty, territory and human rights. Although they have a separate union that protects their rights, not all stateless nation are members of it. And because they lack this affinity they are prone to colonization by other states. Some stateless nation exists in a nation state as a minority group. But as the minority group, some are not offered with equal rights and opportunity than those belonged to the majority.
