The world waits as President Donald Trump might deliver the most devastating news, that has the potential of sending the world into a global crisis. At 2 PM ET on Tuesday (May 8), President Trump will announce his decision about whether he wants to pull the US out of the Iran nuclear deal. The agreement was put into action by former President Barack Obama, and withdrawing from the deal will be the final blow to his legacy.

Donald Trump promised his supporters during his presidential campaign to put “America First,” and now his words will be brought to life if he follows through with his decision. Pulling out of the nuclear deal could definitely devastate America’s allies, and allow Iran to begin developing nuclear weapons.

What is the Iran nuclear deal?

The Iran nuclear deal, formally known as Joint Comprehensive Plan of Action [VIDEO], ceased Iran from making nuclear weapons. According to The Guardian, it involved six countries total -- America included -- to reach an agreement to end Iran’s nuclear program. On July 14, 2015, countries involved agreed to lift sanctions which gave Iran access to the global economy. In return, Iran agreed to curb its nuclear program and allowed nuclear inspections by the International Atomic Energy Agency.

According to USA Today, supporters of the agreement feared that Iran was months away from building their own nuclear weapons. Former President Barack Obama and other world leaders involved believed reaching a peace agreement was the best way to avoid war.

The former president believed that war with Iran was just along the horizon, “Maybe not tomorrow, maybe not three months from now, but soon.” The countries that were involved were the United States, France, Russia, China, the United Kingdom, and Germany.

So why does Trump want to pull out of the agreement?

Trump’s decision could divide America even more and destroy European unity, so why does President Trump want to jeopardize peace? Throughout Donald Trump’s campaign, he called the Iran nuclear deal “the worst deal ever.” President Trump felt that Iran was violating the “spirit” of the deal. Trump accused Tehran -- capital of Iran -- of testing missiles, supporting the Bashar al-Assad and terrorist groups.

This wouldn't be the first time Trump has acted alone or opted out of an agreement, for example, rejecting the Paris climate agreement and recognizing Jerusalem as the capital of Israel. It is all a part of the president’s campaign promise. Putting America first and segregating the country from the rest of the world.

Do Americans want to stay in the Iran nuclear agreement?

In a recent poll conducted by CNN, two-thirds of Americans believe that the United States should not withdraw from the agreement. Sixty-three percent of Americans fear that opting out would grant Iran the permission it needed to make nuclear weapons. Twenty-nine percent of Americans believe that should withdraw and supports the president’s decision.
