The Biden administration had a significant shift at the United Nations security council, abstaining from vetoing a resolution demanding an immediate ceasefire, which significantly isolates Israel.
This shift has been downplayed by the US government, insisting that their policy has not changed, and the resolution is non-binding.
The war is tarnishing the US's international standing, with accusations of complicity in the suffering in Gaza and inefficacy in moderating Israel's conduct.
The Biden administration has failed to translate the idea of conditional US military aid into reality.
Other countries are making moves, Canada is suspending further sales and the UK shifted from abstaining to supporting the ceasefire resolution.
Conclusion: The US's shift in stance at the United Nations is an important symbolic turn, but things are unlikely to significantly change unless the US makes a substantive change.
