Final answer:
Great Britain's Brexit and Trump's trade policies have challenged global integration due to concerns about job loss, sovereignty, and inequality. These pushbacks signal a rise in protectionism and a potential shift away from globalization.
Step-by-step explanation:
Recent events such as Great Britain's vote for Brexit from the European Union and President Trump's stance on trade policies, including his call to renegotiate or end NAFTA, have indicated disruptions to the process of global integration. These events highlight challenges that arise due to concerns over imbalances and policy problems in the current world order. In response to fears of loss of jobs, loss of political sovereignty, and increased economic inequality, countries have taken steps that could be viewed as a retreat from globalization. The rise of trade barriers, as seen with the 25% tariffs on a broad range of imports from China introduced by Trump's administration in 2018, exemplifies such protectionist moves. As of 2022, with the UK out of the EU and changes in the US government, it remains to be seen how these global trade policies will evolve under President Biden's administration.
