Harley Davidson and Mid Continent Nail Corp are some of the US employers being hammered by America's escalating tariffs spat with its biggest trade partners.

Manuela Saragosa asks Vanessa, the author of The Girl On A Bike blog, what Harley fans like her make of the company's decision to move some motorcycle manufacturing from the US to Thailand in order to dodge new EU retaliatory tariffs. James Glassman of Mid Continent explains how the blow from the US President's steel import tariffs may flatten his company altogether in a county that voted 79% for Mr Trump. Plus former US trade advisor Pippa Malmgren explains why it may be wrong-headed for her government to try to address the country's perennial trade deficit in the first place.
