Picking the most emotive term for everything has a very short lived power, everything is a genocide these days according to someone.
The reality is it's a very complex situation with many facets, it's an asymmetric war with very well funded and trained terrorists getting support from Iran and other fundamentalist groups - it's not a small group of innocent people in an open air prison as you want to paint it, there's a huge oil rich and bloody handed gang of despots who maintain power much like any despot by distracting everyone with ideological conflicts - Iran needs the region to hate Israel so they need a war like this, they get their trained terrorists to fire missiles they supply and that's all they care about.
Israel has been making great progress politically in the region, the deal supplying Jordan with desalinated water transformed a crisis everyone predicted to be the start of the water wars into a partnership. With Saudi Arabia moving towards similar partnerships countries like Iran didn't want to sit idle and outy happen. How should Israel and it's allies respond?
Read the article, the world did not say it's a genocide nor did they suggest a ceasefire - you've been caught up in emotive memes probably largely pushed by Russia et all and are using headlines you don't understand but like the sound of.
