After more than a month of questioning, the Israeli Ministry of Defense has now finally admitted that it has launched a "water offensive" against the Hamas corridor in Gaza in an attempt to destroy Hamas's underground network. In response to this change in the Israeli army's style of play, many netizens believe that the "flooding of seawater" will cause a catastrophe to Hamas. To be honest, historically, the "water offensive" has indeed been able to perform miraculous feats in the wars in the Middle East, and Egypt relied on the "water offensive" to catch Israel off guard in the fourth Middle East war.
However, it was only caught off guard, and the war situation has developed to this point, and Israel's decision has instead exposed its huge weakness in front of Hamas. So we can also see that when Israel said that they were going to launch a "water offensive", Hamas did not behave in a panic, how to fight or how to fight, because they knew that things were not as bad as the outside world imagined.
The first thing we must be clear about is that for Hamas, tunnels are not hiding holes. The tunnels they built in Gaza have become an offensive tactic that also weakens enemy reconnaissance, especially in the days when drones are flying. Secondly, as far as any current Israeli "water attack" means against the tunnels themselves are concerned, they are not fatal to Hamas, and they can directly discharge the water through drainage channels and other means, just like our classic movie tunnel warfare.
In the end, there is not only one tunnel built by Hamas, but more than 800 tunnels discovered by the Israeli army, with a total length of nearly 500 kilometers. In the face of the sheer number of tunnels, the flooding of a few tunnels in Israel will have little impact at all. Israel had to flood out of these more than 800 tunnels one by one. And in order to do a good job, Israel also had to move heavy equipment such as bulldozers, cement mixers or pumps to the entrance to the tunnel. It will certainly be easy to transport these heavy equipment to the designated location, but how to hold it is a huge challenge for the Israeli army.
If it can be defended, then the Israeli army will not fight so badly in the face of street fighting, and compared with the Israeli tanks, bulldozers, cement mixers or pumping machines are better to attack and destroy. Therefore, to ensure that these vulnerable vehicles can run on the front line for a long time is to expose a huge weakness to Hamas for the IDF, and if the forces are too scattered, they will not be able to protect the engineering vehicles, and the troops will be too dense, and it will create space for Hamas to operate freely in the Gaza Strip.
In general, if Israel really had the ability to inflict lethal damage on Hamas through a "water offensive", it would have done so a long time ago, not until now.
