There are no odd requests, just requests that will be fulfilled or not. Hamas could have asked Israel to disarm. The agreement is that Hamas will disarm.
Most likely scenario is similar to Hizbollah in Lebanon. They didn't disarm as per agreement, hence no international aid flowing to Lebanon. Israel still controls South Lebanon and kills a couple of hizbollocks fighters on a daily basis.
Hamas is an exception because it believes in martyr death and would drag the whole population in Gaza with them. That is new and unprecedented.
