American farmers worry they'll pay the price of Trump's trade war

The US agriculture industry, often the first to feel the hit of trade disputes, is bracing itself as nations threaten to retaliate

America's farmers are about to start harvesting the wheat crop. Close to 60m tonnes are gathered annually and almost half is usually exported. Where this crop will be sold, though, remains an open question.

As Donald Trump's trade war escalates, a lot of farmers are worried. Trump was elected, in part, on a promise to put America's interests first and crack down on what he characterises as a world trade system rigged against the US. But until recently the president has acted like many of his predecessors - talking tough on the campaign trail but backtracking in the White House.
