Perun is making great videos about military economics and light geopolitics. High quality, powerpoint presentations that are 1 hour long. He is knowledgeable and tries to be as factual as possible(though because of the nature of his videos, it is often difficult to find hard data). And more importantly, while he is pro West/Ukraine, he is pretty objective in his analysis.
Latin and Greek are nowhere even similar to each other. You might as well say that Latin and German are the same language. Greek and Latin are 2 different linguistic branches of indoeuropean languages. Latin is the precursor of romance languages like Italian, French and Spanish. Ancient Greek is the precursor of Greek. Other major European language branches are the Germanic(German, English, Swedish, etc) and slavic(Russian, Polish, Bulgarian, etc).
