Unilateral sanctions against Iran or Cuba without the consensus of the UN is questionable in law in the first place. What crimes have Iran or Cuba committed? And yet these sanctions without basis by countries who count Saudi Arabia as their closest ally are allowed to cause suffering to millions of people for decades on end and no one cares. This is the twisted state of our world.
It seems ultimately foolish to believe in ideals when they only apply to a certain group of countries in their benefit, and when not will use propaganda and their collective political and diplomatic power to harass others.
