A liberal take on treaties: the US must by abide by treaty signed over 100 years ago, and a treaty signed by Bill Clinton guaranteeing sovereignty to the Ukraine must be ignored when it requires US military intervention under a Democratic president, or investigating corruption by Democrats.
a treaty signed by Bill Clinton guaranteeing sovereignty to the Ukraine must be ignored
Was that so-called treaty ratified by the Senate? Of course not.
An unratified treaty is no treaty at all.
