Foreign Nationals captured on the battle field never have had the same rights we do nor did the SCOTUS declare that they do.
Wouldn't it be so nice to try those folks in a US court and the Feds have to give up the CIA op. that worked out the capture of a high value target for example. Way to much classified info that the Feds would not and should not give up during a trial by jury in US courts.
This is a war that we are in and it is a World War with Fanaticist Islamists. The events in India that started yesterday should prove that point.
As POWs those folks should sit in their cozy berths till the war is over or till THEIR COUNTRY negotiates their release. Problem is NO COUNTRY WANTS THEM. If they have committed acts that warrent they should be taken before a military tribunal and tried in that venue.
