In January, Biden published his program in Foreign Affairs. I copy the section that seems more relevant to Israel.
The Biden foreign policy agenda will place the United States back at the head of the table, in a position to work with its allies and partners to mobilize collective action on global threats. The world does not organize itself. For 70 years, the United States, under Democratic and Republican presidents, played a leading role in writing the rules, forging the agreements, and animating the institutions that guide relations among nations and advance collective security and prosperity—until Trump. If we continue his abdication of that responsibility, then one of two things will happen: either someone else will take the United States’ place, but not in a way that advances our interests and values, or no one will, and chaos will ensue. Either way, that’s not good for America.
Basically, he want to recover America's role as universal hegemon, organizing the world so it can function with minimum conflicts and maximum security for all. In the past, that world was good for us. Let's hope for the best. But I would not let him to touch nor kiss my granddaughters.
