There is no international law, there is only "power" in this world if you are strong enough to do whatever you want -- you will always get away with it, the human rights and all the rest of it are just pure propaganda to feed the average joe.
When you spend years studying “international law,” deterrent means, and principles in waging wars, then you find a question in your exams that requires you to answer that international law criminalizes and punishes the violator who violates military values and violates international law and violates its general principles. Then you turn on the TV to see a force targeting a hospital containing civilians and doctors?? Where is the international law they taught us? And why do we even study it? Where are the deterrent means?
I can say with complete conviction that what is known as “international law” is the biggest lie known to human history and that there may not be anything comparable to it in the future.
