No.

Khadr should apologize to the people of Afghanistan whose country he invaded in the company of foreign Islamofascists  , who knows how many Afghans and others were maimed or killed by his road side bombs.

He also should apologize to the people of Canada who he betrayed and to Canada's NATO allies , members of which he harmed directly and indirectly , he was an accessory to say the least.

He should apologize to the people of Canada for taking up arms against them.

He should apologize to the widow he made into a widow and hand over the money awarded him to her.

One hopes that the US judgement against him is upheld and that he does not get a penny for his actions.
