In the past I didn’t really catch that the people were rebelling against the government and suddenly there is great violence against protestors.
I think I missed this completely. I am aware that the beginning was spiralling costs. Is this connected to international sanctions?
The UN doesn’t have any particular claim to the word “international”, except insofar as anything they do is international because the UN itself is international.
Other organisations, or even loosely affiliated groups of nations, can do international things because the word just means something like “between nations”.
That’s pure nonsense. There is only one version of international law and the UN is the only globally recognized organization to enforce it. These other organization are just unilateral tools of specific countries representing their interests. And sanctions such as the ones the west does against their adversaries are unilateral actions by these states.
