When realizing the remaining five members of the Iran Deal are creating new financial instruments to honor their commitments, that includes Russia and Chian. Did Trump decertify from the Iran Deal to assist Russia in creating new financial instrument?
Additionally, Trump wants to end the Intermediate Nuclear Forces Treaty to begin to match China's military buildup. So, rather than engaging in diplomatic methods to bring Russia and China to an enforceable agreement, Trump wants to scape every aspect of the nuclear agreements that control weapons capable of striking 300 miles to 3000 miles of the USA.
This is insane stuff. Trump is destroying the USA's standing internationally and it is doing it as quick as he can.
