Yes seems they don't have to have passports, but some do have purchase them clearly. Maybe be if you are a jihadist it confers some extra credibility to ensure you get through? ( ie there must be an advantage to the $2K spend on one.)
As for Greece and speed of re-location - I was only suggesting that presumably a computerised system is used so that anyone with a passport or anyone who is given papers is logged into a database which is accessible to the next country of passage as they make their way through Europe. Therefore, it seems logical that the computer system would alert to the effect "This person has already entered twice from Syria" etc.
As for refugees I am just as concerned as all of you on here, but I am also mindful that my government and the previous one- who I supported at the time- had some part to play in the de-stabilisation of this area.
No one can, it seems can stop or has a willingness to stop the traffickers and boat owners of Turkey from setting sail across to Greece. Why is that?
Yes wouldn't it be easy if a culturally appropriate country such as Turkey said - "Yes we will create some refugee cities" for the next few years so that all the refugees could camp there awaiting the resolution in Syria.....
How long would they be camped there? IDK, I certainly don't have the answers.
Who knows whose passports they were burning, besides? That they released videos of their acolytes burning passports, shown in MSM, may say something, some twisted youthful validation imagery to attract recruits and also to solidify commitment of the new jihadis.
