You, earlier: "A lot of that ambiguity would vanish if Hamas did not have a habit of not putting uniforms in combat."

Now it's suddenly not a problem? I can't imagine Hamas signed the Geneva Conventions.

German Jews in the 1930s/1940s would probably disagree.

I mean, the IDF killed three Israeli hostages in Gaza, while with their hands up and holding a white flag, because they thought they were infiltrators.

The spirit of the law is reducing the civilian cost of war. Its hard to argue that Israel's few incidents of wearing civilian clothes for special operations increased the odds of civilian costs compared to the same operation done in uniform. Meanwhile, Hamas's lack of uniforms has led to significantly increased civilian cost.
