Will the US ever be able to negotiate treaties/agreements/etc. in the future? [View all]

[Proud Liberal Dem]

With Democratic Presidents making new treaties/agreements/etc. when they're in office only to have them repeatedly overturned, shredded, or withdrawn by succeeding Republican Presidents, how can we maintain the trust of other countries to live up to and honor our agreements (if we even can)? George W. Bush took us out of several agreements that Bill Clinton negotiated and now Trump is doing the same with many of the ones entered into under Barack Obama. How can we solidify these agreements so that we can keep the Republicans from simply walking away from our commitments? This is going to be an increasingly ugly situation IMHO while trying to get any kind of future cooperation with other countries.
