Donald Trump: deal-breaker abroad and at home

The "worst deal ever": That's how Donald Trump described the 2015 landmark agreement that lifted international sanctions against Iran in exchange for the country dismantling its atomic program. In May 2018 the president followed through on a campaign promise and said he would withdraw the US from the deal, which had arisen out of painstaking multi-year negotiations.

In February 2016 then-US President Barack Obama signed the free trade agreement known as the TPP along with 11 other Pacific nations. However, it never went into effect: Shortly after taking office, Trump signed an executive order that took the US out of the deal, thus keeping it from entering into force. The scuttled TPP evolved into a new regional trade partnership — without the US.

The Paris climate accord was adopted in December 2015 after the COP 21 meeting. All 195 participating member states and the EU agreed to reduce emissions, decrease carbon output and try to rein in global warming. The US signed the accord but support was short-lived: in November 2017 Trump told the UN that the US would withdrawal from the accord at the earliest possible date, November 2019.

Trump not only has undone US participation in international climate deals but also has scrapped domestic environmental regulations. Scott Pruit, Trump's head of the Environmental Protection Agency, announced in March 2018 that Obama-era vehicle emissions standards would be rolled back. And at the very start of his term, Trump also said he would review the Clean Water Act and Clean Power Plan.

The ACA, nicknamed "Obamacare," was landmark legislation that roughly halved the number of medically uninsured Americans through program expansion and insurance mandates. Its critics, Trump among them, described it as federal government overreach that would cause skyrocketing health costs for individuals. While total repeal has failed, Republicans did do away with the mandate in 2017 tax reform.
