I don't mention it because it's not the topic of this particular article. I've criticised Israel's treatment of the Palestinians in a few articles recently.
Not everything can be about everything.
But you might want to ask yourself why, in an article condemning terrorism, you feel the need to launch immediately into whataboutism.
I didn’t write a word in support of Israel’s government or their actions. I didn’t write a word against ordinary Palestinians. I wrote about Hamas terrorists and the people who praise them. Whatever you feel about Israel/Palestine, this should be a no-brainer.
