This is why (I think) the previous administration was so intent on calling it 'the war against terrorism.' In a war, it is standard by all countries to keep all prisoners until hostilities cease. So in that sense, it was legal and within the rules of war and the Geneva conventions.

Where they went wrong is they did not afford them the rights of the Geneva conventions to enemies of combat. Instead, they tried to put them into a non-existent category of 'detainees' to attempt to put them into a category that doesn't exist and isn't protected.
