Suprise, politicians are hypocrites. I agree with everything you said.
But this is about Sudan, and it's gotten very bad. I think the most significant difference between Sudan and Israel/Palestine is that Sudan will still exist when the war ends. If Israel cannot defend itself, it is surrounded by enemies that will happily wipe it off the map. But if Israel is not stopped, they will happily wipe out every Palestinian in Gaza.
The Sudanese conflict is about control. The Israel/Palestine conflict is about existence.
