The US foreign policy establishment mostly bypasses the treaty ratification process nowadays because of the embarrassments that occur when they are not ratified. The number of signed, ratified, in-force treaties is probably much smaller than you think it is.

The treaty legal process in the US was honestly not very well thought out to start with - the Congressional oversight role as practiced is treated more like a rubber stamp procedurally. And of course, they are set aside when the establishment finds them inconvenient. It’s mostly settled law the executive can unilaterally terminate or suspend treaties.
