I obviously have not lived through the dissolution of the country where I was born. Still, I do not think of you as man without a country.
But my life, it is here now. But do I belong here also?
I think you answer your own question.
We are all only human. Countries, patriotism, ethnic pride, religions, all the rest of the things, even languages (it is common that a language has one word for those who speak it, and another for those who do not), that humans use to separate ourselves never really change us. We are still human.
Many long forgotten empires and kingdoms have risen and fallen. Who struck fear in all their enemies' hearts in what is now Bolivia 3000 years ago? Whose ruled on the steppes then? In what is now Maryland? Who were the great teachers and poets of Inuit lands while the pyramids were being built on the other side of the world?
All these civilizations have disappeared without even an echo in history. The people born into them lived their lives with them, and some of those people saw the ends of their worlds, too.
They made their lives where and when they found themselves in the context of the people around them. Whether speaking some language lost millenia ago, or speaking English in the US of A today, people make their lives with their loves and friendships.
