Because Hamas kidnapped an Israeli soldier named Gilad Shalit. In 2011, Israel traded 1027 prisoners (including 280 who were serving life sentences) for Shalit. This murderer was one of those released in that trade. As was the current leader of Hamas, Yahya Sinwar. That is where Hamas got the idea that they could pull off the 10/7 massacre with limited consequences as long as they took a sufficient number of hostages. https://bird.makeup/@dovid_hirs53234/1842951226323005762
