Trump exits Iran deal: Here are international agreements that US has quit in Trump presidency

US President Donald Trump on Tuesday, May 8, pulled his country out of the crucial Iran nuclear deal which the administration of his predecessor Barack Obama had made with Tehran along with other major powers to contain its nuclear weapons ambition.

The president didn't care for the international concern over the ramifications of the withdrawal which could see tension getting heightened in West Asia over Iran's nuclear programme.

However, this is not the first time that Trump has pulled out of an international deal. The 45th incumbent of the White House has pulled the US out of a number of key international agreements since taking over in January 2017, reiterating his distrust in the ideas of multilateralism and international cooperation in a pursuit of "America First" policy.

Here are some key deals from which US has withdrawn in the Trump presidency:

Trans-Pacific Partnership (TPP): Two weeks into his term, Trump fulfilled his electoral promise by withdrawing the 12-nation TPP which was a key milestone of Obama's Asia policy. Trump said the withdrawal was in favour of the American worker. His executive order to scrap the deal was symbolic since it wasn't ratified by a divided US Congress. Trump was against the TPP for he felt it was against America's manufacturing interests. Trump's act of pulling out of TPP was, however, praised even by some members in the Opposition Democratic Party, like Senator Bernie Sanders.

The TPP was a trade deal covering 40 per cent of the world's economy which was negotiated in 2015 by countries like the US, Japan, Australia, New Zealand, Canada, Mexico, Malaysia and others. Its aim was to improve economic ties and boost growth, including reducing tariffs.

Paris climate deal: Trump withdrew from yet another Obama-era deal concerning climate change in June 2017, backing the idea that it was a threat to America's economy and sovereignty.

Trump announced on that occasion that the 2015 pact dealt with American businesses and workers unfairly. He though earned applause from his Republican Party but environmentalists, political leaders and businessmen from across the planet criticised the move.

The US's withdrawal from the Paris climate deal was massive since the pact signed by 195 countries was a major effort by mankind to tackle the threatening problem of pollution to the environment. Trump said countries like India and China gained from it but overlooked the fact that the exit of the world's second-largest polluter would defeat the purpose of sustainable development. Trump also said that he wanted to negotiate a better deal.

United Nations Scientific and Cultural Organisation (Unesco): In October 2017, the US and its West Asian ally Israel announced their withdrawal from the Unesco after Washington accused it of "anti-Israel bias".

The US said it would place an "observer mission" instead of continuing with its representation at the Paris-based body. Israel followed suit, calling Trump's decision "brave and mroal".

In 2011, the US was upset when Unesco granted Palestine its full membership despite Israel's resistance for it believes the Palestinians should be given recognition by the UN only after a peace deal is achieved in the Middle East. The Obama administration withdrew funding but maintained its membership.

Though Trump is not the first president to have a sour experience with the Unesco (Republican president Ronald Reagan had also left it to protest its 'pro-Soviet leanings' in 1984 but George W Bush brought it back in 2002) but the current president's disapproval of international cooperation made his exit from the Unesco look starker.

Iran nuclear deal: The Iran deal, formally known as the Joint Plan of Action, is the third major deal that the US has quit before Trump finished 18 months in office. On May 8, 2018, Trump declared at the White House that he was pulling out of the deal, sending shock waves across the international community which was nervously awaiting his decision to reinforce sanctions on Iran. Other parties to the deal, however, did not embrace Trump's decision and it looks the deal would still be in force albeit in a limping state.

The Iran deal was yet another Obama-era feat which Trump looked to demolish from the very beginning as he felt it was "ridiculous" and "insane" and gave the Iranians an unfair advantage. Trump's decision immensely pleased Israel - one of Iran's biggest foes - as it had been alleging that Tehran was secretly violating the deal to boost its nuclear arsenal.

These deals have come under considerable attack:

North Atlantic Treaty Organisation (Nato): Trump though has not officially ended the USA's marriage with the Nato but he hasn't hid his displeasure either. In May 2017, he did not explicitly embrace the mutual aid clause of the Nato at its Brussels summit, keeping the alliance under uncertainty.

Though he formally praised the Nato for its response to the 9/11 terror attacks in the US, he did not commit to uphold Article 5 which says that other allies of the Nato must come to the help of an ally which has found itself under attack.

He also used the occasion to rebuke the Nato allies saying terrorism would be better fought if the members of the Nato paid their fair share for the common defence. He even mocked Nato's new headquarters where the summit took place, saying he didn't ask about its costs.

North American Free Trade Agreement (Nafta): In October 2017, Trump took on the Nafta which features Canada and Mexico besides the US saying it was "possible" that the US dumping the deal which was inked in 1994. Trump said this in the presence of the prime minister of Canada, Justin Trudeau, who was visiting the US at that time. He said if they failed to make a deal, "it'll be terminated", adding that the US needed to protect its own workers. He also refused to call Nafta a fair deal.

Canada and Mexico agreed to the fact that the Nafta could be upgraded but none went as berserk as Trump to call for its end. The USA's immigration issues with Mexico could also leave a major impact on the Nafta as Trump has threatened time and again.
