No one will unite with anyone. A Third World War will definitely happen, and most likely, it will be because of the Americans. And even if there is no war, these two countries will not unite. Simply because we are too different. Unification is only possible if America disappears from the face of the earth and Russia reclaims its territory, which it once sold without thinking. And only then, when countries stop competing, and only when all terrorists and those who can threaten our world die, only then will eternal happiness come.
