Some countries are trying to stop their citizens from going overseas to join Islamic State by either arresting them or confiscating their passports. What is your view on this?

Do it! (Just a Canadian thought)

Let them go...THEN cancel their passport. Don't let the door hit you on the way out!

It's a sad thing, like trying to get a young person dating someone they should not be dating to realize the errors of their ways before something bad happens. Once they leave, they should not be allowed back in, though that is cruel, too. Already some Australians were trying to return to their country but they can't be trusted not to be sleeper agents at this point.

I think we should set up a bureau to help them go.

Make things as smooth as possible.

Even pay for their flights.

It would be a good way to spend taxpayers money.

Just the one proviso, as mentioned above, they have to relinquish their passport and statehood... you know... just to make sure we never see them again.

My vote goes to let them go and they are not welcome back. They've been tarnish at minimum. Murderers and terrorists at most. Or a corpse. Do not pay a ransome, do not rescue them they chose that life.

I'd like to let them go.

However, if they are a citizen of my country I'd want my government to prevent these pathetic individuals from committing murder overseas. I don't want innocent Syrians or Iraqis murdered by a citizen of my country. They are terrorists and it's every nation's duty to prevent terrorism.

One way, all travel expenses paid.

First thing that comes to mind is the government already knows so much about them before they even purchase the plane ticket, which means they already know plenty about you too.

For Pete's sake, if we are living in free nations, free from unreasonable search and seizure (consider the spirit of those ideas rather than 18th century lack of telephone) then spy on them AFTER they leave and there is good reason to believe they have joined some hostile militant group.

As for never letting them come back, come on. People learn and change. Vet them certainly. But just as there is nothing worse than a reformed prostitute the most powerful anti-Islamofascist hero of the future may well be a former Islamofascist who learned the hard but sure and complete way that those nut jobs are lunatics.

The problem isn't whether to stop them going or not. It's all about why they want to go in the first place. If you stop them from going, chances are that they already have a view that would make them radical enough that they may do something in the country that they are being kept in. There would be a possibility that they would then form up much as fascists did in a number of countries before the outbreak of WW2.

The problem can't be cured by closing borders or taking passports away as the affected person will still have the same views, possibly made even more radical by such actions. Allowing them to go isn't really an answer either, for obvious reasons but we may have to weigh the possible outcome up and, in the absence of any other solution, consider making the best of a bad job.

I'd say hand them over to the Kurds directly, so they can be detained before doing any harm.

Let them go!

If you love somebody, let them go. If they return as psychopathic jihadis, they were never yours.
