Greater certainty in trade relations?: understated strategic alliances, vital legislation, trade and regional agreements

It appears the United States Senate may have been trying to make the points that renegotiating or enacting new legislations require more energy, efforts and time than many would appreciate – particularly in the processes and attempts involved in dismantling the Affordable Care Act – an attempt which ultimately proved unsuccessful – even though certain key elements were eventually replaced through the Tax Reform Bill which was approved in December 2017 – the first major legislative success of the Trump Administration. However the Affordable Care Act remains a testimony of efforts which had been invested in designing a legislation – which although not the ultimate legislation for some, still partially addresses certain concerns of the medical system. Certain other agreements have not had it so easy during the first twelve months of the new administration. Notably, the Trans Pacific Partnership, the Paris Global Climate Agreement – and even the North American Free Trade Area (still being re negotiated) – which have either been withdrawn from, or face the threat of being withdrawn from. So which alliances appear to have been understated, dismantled or being re considered, during and following the first year marking the inauguration of the 45th President of the United States?
