Trump claims Nato troops ‘stayed a little off the frontlines’ in Afghanistan

President again disparages allies and tells Fox News he is not sure' Nato would come to US's defence

Donald Trump has again disparaged America's Nato allies, claiming that troops from allied nations stayed a little back, a little off the frontlines" while fighting in Afghanistan in support of the US campaign against the Taliban.

The only time Nato has ever invoked its mutual defence clause - stating that an attack on one member represents an attack on all - came after the terrorist attacks of September 11, when member states deployed thousands of troops to Afghanistan.
