Would you rather I call it by some fluffy, feel-good term like special operation? Elimination of the enemy? Opening a retaliatory assault on the Gaza strip while running a propaganda campaign aligning Hamas with groups like Isis or the Nazis, and portraying the Palestinian people as wholly supporting Hamas does nothing but provide justification for civilian casualties.
You are correct that a country may not normally provide advance warning of assault, however an unreasonable warning is as good as no warning and again, only serves to justify the deaths of any innocents that weren’t able to evacuate in time.
Israel has one of the best special forces units on earth, total control of what comes in and out of the strip, and the funding of the world’s second largest military, and you seriously believe they need to commit to clicking the delete button on the Gaza strip to remove a militant group from an area smaller than new york?
