Article 5 of NATO

 This is a quote from the BBC website:

"UK Defence Secretary John Healey says British troops who died in Afghanistan should be remembered as "heroes who gave their lives in service of our nation".

After Donald Trump's claim that Nato forces stayed "a little off the front lines" during the conflict, Healey points out that UK and Nato allies "answered the US call," the only time the alliance's Article 5 has been triggered.

"More than 450 British personnel lost their lives" in the conflict, he writes on X.

"Those British troops should be remembered for who they were: heroes who gave their lives in service of our nation."

Nato's Article 5 states that an armed attack against one member "shall be considered an attack against them all"."
