I don't know how to confirm this myself but I have read and heard that before anything else, after it was known Hamas fighters were inside Israeli territory, the IDF first move militarily was to start bombing Gaza. No one can argue honestly that the IDF defends Israelis - its literally just the most reactionary of religious Zionists that they serve.
Secular Jewish Israelis? Nah they can fend for themselves for a few hours, we've gotta attack Palestinian civilians, says the IDF. And that's not even bringing up that 20% of Israeli citizens ARE ARABS, some of whom were also attacked in their homes in Southern Israel 10 days ago, but of course the same people calling Hamas human animals will go after them next (not to suggest they aren't already, only that Gazans face more immediate extermination).
"We can afford anything when it comes to protecting our international position and pursuing national interests."
Unfortunately, international relations has never really cared about poors - if you study diplomatic relations they literally teach you that "human rights" wasn't even a concept to foreign relations between nation-states until the 20th century.
