This is not accepted fact anywhere but conspiracy land, there are articles saying that Israel have been far too soft on Hamas by letting aid through, limiting the effectiveness of bombing missions to limit civilian casualties, and ending prior conflicts before totally destroying them. These are all things which the international community loudly calls for, you can’t be pro Palestine and say that Israel is responsible for Hamas because they have ceasefires and allow aid deliveries - you’re using hardline arguments to call for a soft line, it doesn’t make sense
