'Terrorist' is a shorthand for 'Terrorist we don't like'

Looks to me like a natural choice: the visible head of Hamas, which is the enemy. I don't think Israel is interested in peace negotiations, so it is also a way to say they don't care and they will wipe out everyone there. Which is in line with everything else Bibi & company have been saying and doing.

Sounds like a good strategy to me. Exploiting an enemy's weakness is standard practice in war.
