In the Hamas/Israel war, why does Palestine have "hostages" but Israel has "prisoners"? - lemm.ee

This occurred to me while listening to the news. When they exchange people it’s always hostages for people held in Palestine and prisoners for people held in Israel. Why is that? Is it just perception or is there a practical difference?

Israel put people in jail for crimes which were illegal. Hammas kidnapped random people, many from a dance club.

Well this is factually just not true. Israel kidnaps many Palestinians even children without evidence and releases them after a “holding period”.

They often do this just to bully Palestinians in the west bank.
