The tnyt title looks accurate to me: it says Israel is striking Lebanon AND that Israel is casting these strikes as pre-emptive.
The title is not saying that tnyt believes that the strikes are actually pre-emptive, instead it’s reporting that Israel claims that the strikes are pre-emptive. Which is accurate, since Israel does in fact claim that.
Yep, this is a good example of what actual inaccurate/deceitful reporting would be like. Unlike the headlines in the post of the op, your made up title is reporting things that didn’t happened, and your quotes are not things that Hamas’ spokespeople have said. It is vaguely based on things that have happened, but it’s mostly just made up and thus completely inaccurate and deceitful.
The point being made is that they’ll harp unconditionally any old bullshit coming from Israel, putting it in a position of prominence, but not any old bullshit from other sources - even when they say the quote cones from sources in the Israeli government, merely choosing that for prominent position is already promoting it and that source.
Selectivelly and reliably quoting just the one side or always giving more prominence to what is said by just the one side says is an old Propaganda trick for when the Propagandist does not have full information control, and works by the same principle as exploited by lots of far-right populists to rise on saying controversial bullshit and on the criticism of their adversaries: anything given prominence and more attention is internalized by readers/viewers a being more important.
Actual Journalism would treat both sources equally.
Unlike plain-old-lies, such Propaganda Techniques can only be confirmed as such by measuring lots of articles from a news outlet and statistically analysing the words they choose and where they use them by comparison to other outlets, as pointed out in Linkerbaan’s post.
