1. Hamas is the government. It's hard not to enlist or be commondeered.
2. If you haven't seen any of the videos of the blockades and checkpoints or heard the first hand stories of how they can't get pencils or baby formula or seen the Israeli troops get into armed conflict with red cross and doctors without borders... Like come on. You know why they enlist.
As for the old men... Both sides do want genocide.
It is spoken and written from the highest echelons of both governments. Explicitly.
Everyone suffers. But both powers want a 1 state solution. It's gross and sad.
