What does Biden’s order against Israeli settlers mean and why did he do it now?

Some see the US president's executive order imposing sanctions on settlers who violently attack Palestinians as a bid to win support

Was Joe Biden's announcement of unprecedented US sanctions against Israeli settlers in occupied Palestine a sign of political weakness at home, or of a newly found willingness to assert American influence over Israel?

The president signed the executive order imposing financial and travel sanctions on settlers who violently attack Palestinians shortly before a campaign rally in the swing state of Michigan, where the largest Arab American population in the country has rounded on Biden over his largely blanket support for Israel's assault on Gaza.
