Who&#39;s responsible?

Aviva Shalit, the mother of kidnapped IDF corporal Gilad Shalit, has sent a letter to Prime Minister Netanyahu.

Aviva Shalit, the mother of kidnapped soldier Gilad Shalit, sent a letter to Prime Minister Benjamin Netanyahu marking 1,600 days since her son fell in Hamas captivity, and wrote: "I don't know what else to say for you to wake up.
"Gilad is alive in Gaza. I don't know if he will be alive tomorrow. You and only you are responsible for his life. Please don’t share this responsibility with cabinets and generals, only to brush it off your own hands," the letter read.
I would say that Ismael Hanieyh and Hamas bear a lot more responsibility than Netanyahu does. They kidnapped Gilad Shalit, they are holding him, and apparently there is no reasonable price for which they will release him.
