"Everybody knows who is responsible - they have records of war crimes as long as your arm
If you have any information, give it"
Come on Jim where is the evidence?

Many many allegations no evidence.
You know what they say:- If you repeat a lie often enough, people will believe it, and you will even come to believe it yourself.
You Jim, are a fine example
I cannot prove the allegations one way or the other-conversely neither can you.
This does not fit your agenda so you resort to the usual bluster and insults.
