I think Donald, no need for hypotheticals.
Israel’s “Hamas terrorists” hasbara has been smashed to pieces in 2014. Yes, there’s rockets, which are an irritant and may or may not constitute a war crime; I’ve seen Qassam claim to be targeting Israel’s military targets.
Then there’s the tunnels, dozens. Hamas could easily have attacked civilians squatters at the kibbutz so near Gaza, but they chose not to, just IDF.
