On February 21, 2010, three days after North Korea declared it would not abandon its nuclear weapons program, Pascoe, who had just visited Pyongyang, strongly defended international food aid to the country.

"These are human beings that need the food.
It's not the political system.
This shouldn't be argued in a political way," he told CNN's Christiane Amanpour.
