Israelis hit back hard. But they haven't been the ones to declare war on peaceful neighbors.
It wasn't them who stood for thr München massacre or a number of plane hijackings in the 70ies.
It wasn't Israelis who blew up buses in Gaza.
Was it?
We must stop confusing powerful with evil and currently helpless with "innocent".
The modern state of Israel with its present borders were a creation of the Second World War. But if you go back in time to ~1000 BC, Jewish people occupied the entire region (much broader than just Israel), and they are the only surviving indigenous people of the region. This isn’t even controversial. Virtually all historians and scholars acknowledge this because there is literal physical evidence in the buildings at Temple Mount and elsewhere, which are all dated back to that time.
You will probably also like to know that the plans for a modern Israel started long before WW2 and Holocaust, and originally not because of persecution of Jews by Europeans in Europe but because of persecution of Jews by Arabs in the middle East.
