In my opinion it was a very well planned move, not a technical mishap. Israel is a country which measures its every move with super-precision, such a technical mishap has a low probability of occuring. So I believe Bibi is lying. But, let us assume that it is not a lie, let us assume that it was really a technical mishap. Then it means that Israel WANTS bu build these settlements but it was not tactful to announce it during Biden's visit. This means Israel is lying when it says it is supporting peace with Palestinians and it accepts a two-state solution. You do not support peace by building 1600 heavily weaponized settlement in West Bank. You do not support the two-state solution by building 1600 settlements in the heart of an alleged future Palestinian state.
