Rather, it is a mix. Some crazy like Zionists / Jews stabbing Germany in the back during WWI, declaring war on Germany in 1933. Some mostly truthful like the attack on the Liberty. The distortion of history is a huge danger here.
The actual history shows that Germany horribly victimized the Jews and the existence of Israel is largely a response to that – while the Palestinians are equally innocent victims of Israel. The Arab / Palestinian side moreover has been striving for peace against generally war-mad Israel who usually imitate that German rather than sane behavior. The Arab “side” would do best to be fanatical about truth and never exaggerate anything. Like the Jewish people and the other millions of victims against WWII Germany, their case is so strong anything else weakens it. Karim Khan appears to be doing the exactly right thing. Both morally and practically.
