It's quite sympathetic with all you have said.
But one bitter truth is that, it's not in your place to hurriedly determine or say Russia is commiting crimes against humanity. We have the UN and other organizations alike, let them stand up to their duty and save the world before this situation escalate beyond the normal.
UN is doing nothing. Their duties can be described as claiming their “concern”. There were obvious reasons days ago to stop Russia from ruining civilian buildings and killing innocent people. There were multiple video evidence, where Russian captive soldiers admitted they had an order to do this. It is not a secret for UN and other organisations. But they choose to ignore this.
This situations has escalated beyond normal 13 days ago. We are trying to convey to the world that drastic measures must be taken before it is too late. That’s why, it is my duty, as well as it is duty of all Ukrainians, to stand for our country. Because no one will do it for us.
