I showed you abstractions in the UN listing on the Geneva Conventions that showed economic warfare is illegal.
I just did not search the actual UN regulations because they are huge, with many sources, and over long periods of time.
Economic sanctions against Iraq for example, where notorious for causing starvation.
Which is why the US finally allow OFF, Oil For Food.
But that was still illegal because it did not allow market value for the oil.
All economic sanctions always hurt food imports because they reduce the nation's income they need to be able to buy food.
And economic sanctions are against US law because they take aways the ability of US citizens to make a living if they had previously done business with a country that is being cut off, without any compensation.
It is illegal to stop any US citizen from doing business with anyone, without compensation.
