Israel's attack on Hamas' top leaders as they weighed a new ceasefire proposal in Qatar was the latest in a series of shocking and unprecedented measures it has taken to vanquish the militant group — all of which have so far failed.
Hamas says its top leaders survived Tuesday's strike, but it has offered no proof and has been tight-lipped after past assassinations. But even if the strike did succeed, it wouldn't spell the end of Hamas, which has survived two years of war and still holds around 20 living hostages in the Gaza Strip.
