I wrote an answer but it's invisible.

I can admit I am not completely up to date on this, but can someone answer this for me? Why is it Israel's responsibility to provide electricity? Should they be looking to to do it for themselves?
The Gaza strip is a completely isolated piece of land. During the Israeli ocupaiton, it was Israel's responsability to provide the services required byt he population, but for obvious reasosn they made sure to plug services to outside networks, and thus Gaza's abbility to produce its own electricity is pretty low. All they got is old equipment dated to the time of the British occupation, and which was designed for far less people than it lives there now.
Put in short, Gaza obtained its power supply from Iasrael as Israel didn't wanted Gaza to have its own power supply, and so now Israel can just pull out the plug and leave Gaza without power supply. Provided that Gaza is utterly poor, its economy is a whole disaster as its main business partner is Israel and its main employer is Israel, then Gaza can't live in the civilized world if Israel denies them the services, as consequence of israel's own occupation policy whose aim was, of course, precisely this.
Which leaves us with the uncomfortable question of what is the name of it when a State undertakes a
collective and
undiscirminated punishment against a
civilian population.
Or, as this cartoon told...

Gaza's status has never been that of an independent nothing, but has always been an occupied land (owned by the Brits, by Egypt, by Israel) wiht all the inconveniences from it... and a hostage civilian population currently trapped between rocket-throwing heartless motherfucckers and mass-punishing heartless motherfuckers. Business as usual.
