I'm not sure it's possible to look at what Israel is doing and say it's not terror. So, charitably, I guess you're saying the IDF is not an organization?
Usually, you can argue that a state's actions aren't "terrorism" because most definitions of "terrorism" involve the requirement that the action is illegal. But saying that the IDF is regularly committing war crimes isn't even controversial at this point. So what exactly separates their illegal actions intended to instil terror from all the other terror organizations?
IDF is a real military with rules of engagement and target selection. If you say indiscriminate bombing, no this is not. WW2 and Korean War was.
