The act of publicly destroying ones passport is a powerful political statement, but one thing I deduce from the spectacle of a throng of young men burning their passports — it’s reasonable to assume they did so while in Syria — is that these are young men who are not making travel plans. At least that’s what I deduce.

Patrick Cockburn thinks otherwise:

It is only a matter of time before jihadis in al-Qa’ida-type groups that have taken over much of eastern Syria and western Iraq have a violent impact on the world outside these two countries. The road is open wide to new attacks along the lines of 9/11 and 7/7, and it may be too late to close it.

Those who doubt that these are the jihadis’ long-term intentions should have a look at a chilling but fascinating video posted recently by the Islamic State of Iraq and the Levant (Isis), formerly al-Qa’ida in Iraq. It shows a group of foreign fighters burning their passports to emphasise their permanent commitment to jihad. Many of the passports thrown into the flames have grass-green covers and are Saudi; others are dark blue and must be Jordanian. Some of the fighters show their faces while others are masked. As each one destroys his passport, sometimes tearing it in half before throwing it into the fire, he makes a declaration of faith and a promise to fight against the ruler of the country from which he comes.

A Canadian makes a short speech in English before switching to Arabic, saying: “It is a message to Canada, to all American powers. We are coming and we will destroy you.” A Jordanian says: “I say to the tyrant of Jordan: we are the descendants of Abu Musab al-Zarqawi [the Jordanian founder of al-Qa’ida in Iraq killed by US aircraft in 2006] and we are coming to kill you.” A Saudi, an Egyptian and a Chechen make similar threats.

These can’t be dismissed as idle threats, but neither can they be treated as imminent threats.

I would surmise that whoever burns their passport in Syria probably expects to die in Syria.
