Ahem, Ireland did not support Hitler.
Ireland stayed neutral , on the side of the allies, during the 2nd World War.
This was after Ireland had huge casualties in World War 1, was still denied it's independence despite promises to the contrary for supporting that War effort, which led to a rising in 1916 and ultimately an Irish civil war over the settlement imposed on them by the UK. This was after already approximately 800 years of oppression from a brutal, colonising neighbour, who had also presided over a genocide during the Irish famine, when Irish farmers had to export their food instead of feeding the starving local people, including many family members
Israel are now inflicting a famine on the people of Palestine. This is a fact. They are doing this by blocking humanitarian aid to the oppressed and starving Palestinian people. It is not anti semitic to state this fact. The UN have stated this repeatedly and Netanyahu is wanted by the ICJ for war crimes, genocide & crimes against humanity.
