No treaty is completely safe from unilateral action. But certainly those arrived at by acts of congress are much more durable than those established by executive order.
Only if Congress exercises it's constitutional power to compel the executive to abide by duly ratified treaties or remove said executive for usurping it's powers. It has so far declined to do so in modern history. Ratification would not have protected the Paris agreement or JCPOA in the current political paradigm.
