It’s simply that she, like every other israeli, did national service (with the IDF). Presumably at some point a good deal of years before she was in WW. Because it’s typically for 18 year olds.

Now, absolutely nobody was mad about this at the time she appeared in wonder woman, but they are now that the war has flared up.

This is why there’s been a little campaign of vitriol about her wcting abilities, too. I just think that if people actualy cared about these things they would’ve complained about them some time before Palestine entered wider public conscience. It’s common knowledge that israelis have to dk military service with the IDF, after all.
