Explanation:

A confederation is a union of sovereign groups or states, united for purposes of common action. Usually created by a treaty, confederations of states tend to be established for dealing with critical issues, such as defense, foreign relations, internal trade or currency, with the general government being required to provide support for all its members. Confederalism represents a main form of inter-governmental-ism, this being defined as any form of interaction between states which takes place on the basis of sovereign independence or government.

in president trump’s administration, there is a national security presidential memorandum that "strengthens the policy of the u. s.", affecting trade with cuba.
