She almost certainly didn't do either of those. Most soldiers in an army will never fire a weapon. The majority are on the back line or at home.

This isn't to excuse her. She supported Israel in other ways whole they did horrible things. However, most people are reluctant to leave their homes and their families, and most won't do anything particularly objectionable (actively) while in the IDF.

This is a real naive take. It would be nice if we could all stand for our morals, consequences be damned, but the vast majority won't and I don't consider people to be bad because of a choice between two shitty options.

I really wonder what you would actually choose to do in such a situation. It's easy to armchair. Not as easy when you actually have to make the choice. And I'm saying this from experience with choices far less consequential.

The last part, yes.

I don't have any issue with Russian people either. It sucks what they're being forced to do, and should be killed because they're being used to invade another nation. That doesn't mean I'll hold it against them if they decide to work with us against the Russian elite that are causing the issues.

Don't make potential allies into enemies because of their past. Gal is not a potential ally. She's an Israel sympathizer. That's the thing that's bad about her, not that she served in the IDF.
