Why does IDF feel the need to release a new video every time they "discover" a new tunnel?

They document it because nobody outside of Israel believed them on anything. Now are people getting mad because they are proving themselves right? At first no one believed Hamas had a elaborate maze of tunnels. You say it as well known. If it was so well known then why did the anti Israel groups not believe them?

No one denies the tunnels
Even Al jazeera mentions them
Al Jazeera is heavily pro Palestinian
In fact tunnels have been used in warfare in the past
And seeing how Israel has an army and it’s the oppressive evil character in the story
and Palestinians don’t have a state nor an army it’s not hard to understand why they use tunnels
Even the Jews in Warsaw ghettos used tunnels and bunkers
However
It’s the unsupported allegations of Israel saying that Hamas is under the hospitals which Israel used as an excuse to bomb almost every hospital in Gaza thus destroying almost the entire medical infrastructure which is a a war crime .
And even if Hamas was under those hospitals
It does not make it okay to bomb civilians
Otherwise the 7th of October is justified
Since many people in the Israeli forces were in the mixture of the civilians
Furthermore, many soldiers and those in Israeli forces are in reality nestled in civilian areas in Israel (true name:occupied historic Palestine )

By the way ,
The entire reason Israel exists is because of tunnels and civilian infrastructure used by Jewish milita.

Isreal is feeding the media. The media is feeding American voters. American voters are not protesting the American govt support to Isreal on this genocide.
So isreal has to keep posting to get american support. Without america they could get wiped off the face of the planet.

There is a lot of doubt as the Left thinks Israel’s goal is the murder of the 2 million Gazas.

Israel, namely Ehud Barak, the Israeli former Prime Minister, was very matter of factly about the fact that Israel built all the tunnels under Gaza's medical facilities. He said it a few weeks into this latest round.

What the IDF is trying to do, is show that these tunnels are used for military purposes.

It keeps them in control of the narrative.
Let's ignore the killings of civilians...17k and counting....but hey: We found another tunnel!

You said: "Propaganda and excuses are what we expect from Hamas - not Israel."

Is that how you see it?

They think we're dumb enough to be distracted from the main point, which is the genocide of the Palestinian people.

Trying to justify their genocide campaign I imagine
