Does Israel have the right to exist ? Not according to international laws

Here’s a quite interesting video underlining crystal clear that while people certainly have rights within civilized spaces on Earth, there are no such concept in the international laws corpus pertaining to the right of a nation or of a state to exist.

■ BY ORGANIC REALITY and NATURAL HISTORICAL DEVELOPMENT, an existing nation is a group of peoples having more or less decided — sometimes if not most of the times for the average persons, it’s rather the historical circumstances which decided for them — to live together for centuries if not millennia, often sharing a common language, common habits, religious beliefs or otherwise beliefs and a certain recognizable pattern for socio-politico-economic organization.
Simply said, a nation is a bunch of glorified tribes having more kr less achieved an ackniwledged place under the sun by the other nations. That acknowledgment might change with the dynamics of the always shifting international balance of power.
