I can’t see why a democracy can’t elect a government capable of evil. History has also shown us that - repeatedly - particularly in context of colonialism when the victims are dehumanised and othered.
The decision making in Israel seems to be skewed for a reasons- a need to hold onto power, a coalition is held together by extremists, the country itself has experienced terrorism on a mass scale - can you not see how it could create conditions were a democratically elected government succumbs to the acts of cruelty itself. It’s happening both in Gaza and WB.
I understood your concerns but no country should be immune to rightful criticism.
Unfortunately - some of Israel’s citizens do hold extreme views, which support ethnic cleansing of Gaza- for example - but again - this is understandable. There are also still truly liberal Israelis and their voices need to be heard more.
