If anything, pulling out of those agreements could merely be seen as a “regrouping” effort by the United States, in order to once again find its “sea legs” and “reboot” before going back full blown into the world of international commerce, trade, governance, or relationships.
But pulling out of, or otherwise violating, the Joint Comprehensive Plan Of Action (otherwise known as the “JCPOA” or “Iran Nuclear Deal”) would be a monumentally huge and stupid thing to do, considering what is on the line in doing so.
Right now the only result of outright international warfare, resulting in the drawing in of massive continents and sub-continents, as well as technologically sophisticated nations, would inevitably lead directly to nuclear war, in other words, the end of humanity.
In that case, people would die, billions of people exactly, if not the entire global population now approaching 9 billion souls internationally.
This is not a risk anyone should take, and the JCPOA, negotiated by the P5+1 nations (China, France, Russia, the United Kingdom, and the United States; plus Germany) with the U.S. being represented under the President Barack Obama administration by Secretary of State John Kerry, represented one of the greatest diplomatic achievements in human history in order to avoid World War III, and restore balance and peace to the “Force.”
Respecting the JCPOA deal should be of paramount importance to all of the world’s leaders, not just the ones being restricted.
To that end, if North Korea’s Kim Jong-un ever decided to approach the negotiating table at the multiple requests of South Korea’s President Moon-Jae-in, and countless other world leaders, including President Donald Trumps’ cabinet members and staff such as Defense Secretary James “Mad Dog” Mattis and Secretary of State Rex Tillerson, then the U.S.A. needs to be able to stand straight up, look at the North Korean leader and his Staff straight in the eye, and say with total confidence that “you can trust us.”
Otherwise the U.S.’ word is as good as a pile of dog refuse, and no one would ever enter into an international treaty or agreement voluntarily, giving up their nuclear/biological/chemical stockpiles, ever again, and they would have every reason not to.
There is no wiggle room on this one – the Iran Nuclear Deal managed to single-handedly disarm the nuclear ambitions and progress of the Iranian government without firing a shot, and if smarter cooler heads prevail, perhaps the U.S. can now follow suit and eventually do trillions of dollars of business with them, just like the Europeans are starting and trying to currently do.
At the end of the day, the U.S.A. needs to remember the wise words of one of its greatest Founding Fathers, Thomas Jefferson, when he declared, “Peace, commerce and honest friendship with all nations; entangling alliances with none.”
Because the only thing that really protects and safeguards different nations from attacking or being attacked by other nations, is when their mutual business relationships and monetary/financial/economic health are hopelessly bound together, just like the air that we breath, and the planet that we share.
