But the amount of aid going into the Gaza strip has increased dramatically (up to the Rafah crossing being taken). i.e. Israel did take action on this matter.

EDIT: It's also important to note the odd timing of asking for arrest warrants for the Hamas leadership at the same time as the Israeli arrest warrants.

Clearly unlike Israel there is no chance in *$#@ that Hamas would prosecute their own leadership for violation of international humanitarian law. The Hamas violations have also occurred earlier.

I.e. Israel should be given more time for its independent legal system to evaluate whether or not there's a case and pursue it. Israel justice system has put prime ministers and presidents on trial. Hamas shouldn't be given any time.

Given this you'd think arrest warrants for Hamas leadership would come a lot sooner.

Since this isn't the case one has to wonder if the prosecutor is doing a "both sides" kind of thing, maybe afraid of backlash if they only go after one side, in which case the response of Israel to the request to increase aid (which has happened) is not relevant.
