From what I've read, Welshwife, most of them do want to go back.
The bravest people I can think of at the moment are the White Helmets. However, if most of these Syrians stayed in Syria, their work would be so much more onerous and difficult. Apart from that, many towns and cities are being systematically starved by the Syrian government.
There is nothing back there for them.
The people in the fifth richest country in the world should show a bit more compassion for these children.
As Welshwife says, they probably were children when they left Syria.
Another of the terrible things that this government does is allow children to try and claim asylum, then send them back when they reach 18. That's immoral, in my opinion.
