it was to make a point that their policy was in disagreement with things they had promised the US.
Just a quick clarification: The building of homes in Jerusalem is not a change of policy; Israel did nothing in disagreement with their promise to the US. The promise Netanyahyu had made (and which Israel continues to honor) was for a 10-month moratorium on building in the West Bank settlements (but which expressly excluded East Jerusalem).
Speaking of the West Bank, I think it is interesting to note that two things happened during Biden's visit. Israel's board of urban planning announced it had approved some new homes in Jerusalem. Meanwhile, the Palestinians renamed a square in the West Bank in honor of Dalal Mughrabi, a terrorist (well, they call her a 'heroine' and a 'martyr') responsible for killing 38 Israeli citizens, including 13 children, during the infamous Coastal Road Massacre.
