From Zero hedge art:
In a letter addressed to President Donald Trump, with copies to the International Criminal Court (ICC) and the UN Security Council, four top former officials at the highest level of the US government have given him legal notice about his duty to advise the US Congress, the ICC and the UNSC, among others, about Israel’s actions coinciding with the “70th anniversary of the expulsion of 750,000 Palestinians from their homes.”
This is not a legal letter. It is given to the ICC, to which the US is not a signatory, and in which this would never make it to the prosecutors desk. Potus has no duty to inform congress about Israeli actions. And the US holds veto power at the UNSC. This is theater only, and can safely be ignored.
