Your post is a list of grievances, none of which justify Israel's unilateral and internationally opposed terror bombing of Palestinians. Being unhappy with international consensus doesn't justify war crimes. Claiming someone else committed war crimes doesn't justify war crimes.

As for your demands, nobody has to explain how to get Hamas to do anything, because that is a goal whose priority is secondary to preservation of civilian lives against the terror bombing of civilians which is ongoing as we speak. Israel must stop, and only THEN can we discuss how to deal with the next issue. The priorities are, in order of highest to lowest

1. Stop violence currently being perpetrated against civilians (address most immediate ongoing harm)

2. Stop blocking aid to civilians (address less immediate ongoing harm)

3. Discuss/Negotiate security for civilians (address future harm)

3 doesn't come before 1 or 2.
