If you take what happened in Israel and change the location to London, do you think UK would just shrug it off? I am in no way saying what is currently happening is okay, but the response was the response, replace Israel with most other military dominant countries and you would get a similar response, especially if you were the stronger party. Depending on who we talk about, it may actually have been way worse.
I believe what OP is saying is that most other countries would have done the same. And for you to impart hatred on Israel for doing what most other countries would have done is anti-semitism.
