The current US leadership are themselves are not in a particular place of credibility when it comes to maintaining treaties and other international commitments.
Treaties also help frame, and provided mechanisms for detecting and limiting, cheating.
Which is particularly important if, like any democratic country, you need to build consensus for moving in any particular policy direction (especially for those that demand so much resources and the opportunity costs that come with that).
And trying to imply that “pressure groups” that happen not to share your views are somehow traitorous is often seen on this forum but no less dishonest and despicable for it.
And completely counterproductive to what you should be trying to do which is to try to convince other people, instead of alienating them.
Terminating treaties does not equal cheating on treaties. Terminating treaties where cheating invalidates them is the corrective action. Hard to grasp?
Treaties between democratic countries and non democratic countries require broad consensus or the non democratic country can use the internal opposition to cover for their violations. Where is your counterpart in Russia?
A better description of despicable is substituting "traitorous" for opposition and them condemning the substitution.
Your last sentence proves again that you will never be accused of self awareness.
