If the US were to try and meddle with the Iran deal, it would end up as loser.
Whatever the new US administration’s policies, to mess up with the Iran deal would result in Tehran emerging the winner. Even sanctions would no longer work. The Europeans are already lining up for trade with Iran. China, Russia, India, etc. all are signing contracts, including military and business.
The 21 members of APEC that constitute one-third of the world’s population and half the world’s trade recently met in Lima, Peru and China is taking the lead. US President Barack Obama has joined the campaign against scrapping or changing the Iran deal but he is a lame duck president and can do little. South Americans are joining Asian economies to fulfill their needs.
