How and why do you think that right wing nationalism has arisen in Israel? Israel was founded on broadly socialist principles.
How many times have the Palestinian leadership turned down settlements and two state solutions over the decades? How many intifadas and campaigns of terrorism can any nation tolerate?
You do realise that words have meaning. War is not the exact same thing as genocide. Have you witnessed Israel transporting muslim arabs from around the Middle East into Gaza in cattle trucks - to especially designed gas chambers?
Israel is a modern, democratic country and all citizens have equal rights - and that includeds the 20% of the population that is Arab - Muslim. Everyone has the vote, can sit in the Knesset, and take up any role or profession in society.
Until Hamas and other extremist organisations cease with their jihadi campaign, israel will do what it has to do to secure its borders and defend its citizens. War aims are standard in any conflict but war in and of itself is not genocide.
If genocide is your main concern i take it you have a lot to say about what is going on in Sudan at present, or what has been going on in Northern syria, or any number of other places in the world?
Or maybe you are just on a bandwagon, and when that wagon departs so will you.
