The article details the plight of some Americans working in agriculture who will likely suffer under the economic fallout from America's withdrawal from the TPP. The other countries that were involved in the deal have been trying to salvage it, which has included the formation of a potential series of smaller trade alliances that will likely undercut the US' agricultural exports.
The demise of the TPP has also reduced the US' "soft power", increasing the trade influence of China and denying Washington the ability to leverage its superior position to force Beijing into action on North Korea.
Anyone who has interest in economics or international relations please provide your thoughts on how the US should act moving forward. Is it doomed to an irreversible decline in its fortunes and power projection?
