Turkey has done more for migrants than any other. If it weren't for Turkey many more would be heading for Europe.

Internment may have worked in WW2 but it certainly wouldn't work now for reasons already stated. Terrorism isn't new to the UK as has already been stated. You've got more chance of being killed in a car crash than by a terrorist. People need to stop making irrational calls for the government to do something and get some perspective. Threats can be mitigated using all the methods already in place via the government's CONTEST strategy. It's already helped foil many attacks and probably prevented many others.

Making far reaching decisions on impulse immediately after an incident is usually a bad idea. Better to consider the evidence soberly and act on reason rather than instinct.

I am more than happy with my news sources. Government and eu migrant statistics show one million three hundred thousand migrants applied for asylum in the Europe area in 2015. Germany alone over the last few years have absorbed one million migrants. Are you suggesting this human tidal wave has stopped. I have not even factored in the vast amount of migrants in camps in turkey.
I note that the Manchester bomber is from a family of Libyan refugees. He was also given the chance of higher education which he decided against. His gratitude for this humanitarian gesture was to blow up a group of sweet young and innocent children.
Certain politicians of recent years need to beg the forgiveness of the British public for creating this situation.
Just think about what we are witnessing today, armed police on the streets of Britain protecting the British population at large from attacks from its own citizens. My father fought for his country and spent years in a prison camp , to see this would break his heart.

What were your views when the IRA were carrying out bombings in England ?

Although it's not palatable, at some point there will need to be dialogue with the leaders of ISIS and their ilk to find a long term solution, assuming that there may be one.
At the moment, everyone is rightly outraged but, that wont stop a repeat of this, either in the UK or, elsewhere.
The aspect of this that disgusts me most is that it is being done in the name of religion and perhaps if the religious leaders of all faiths started preaching a slightly different message, we may actually have a better world to live in.

I’m not sure a dialogue with so called IS would achieve anything since their aims are so incompatible with civilised values. We didn’t negotiate with the Nazis so why negotiate with so called IS? Who do they speak for? They don’t represent any population. They are a death cult.

With long term policies to fight them and to simultaneously alleviate the conditions that brought them about they can be defeated - just like many other extremist groups in the past e.g. Kymer Rouge.

Negotiate with isis, think you would end up minus your head. The absolute stated aims of isis is to bring down western civilization by any means possible. That includes extreme violence .
Not certain why you introduce the ira into the debate. Obviously a political settlement was reached with them. A situation which is impossible with isis.

But you can do it if there is a will. We stood for greater decency at the time of WW2 and did it. Families and associates do generally know or suspect these things. Also, the criminals need to show their actions / intentions have wider consequences than just to them (after all if somebody is content to blow themselves up there is little to gain from just affecting them).

You talk about going against what we stand for. What nonsense. Terrorism has affected our everyday lives enormously - surveillance, bag checks, snooping on internet usage, army on streets, etc, etc. What would help us restore our way of life is to deal with these people harshly - remove their freedom and rights for the benefit of the vast majority. Anything else just erodes everybody's liberty over time. The only way to uphold values is to be tough on those who seek to undermine them. Nothing else can work.

It is not the only way. It is one strand but to believe these people are wholly influenced by clerics is naïve.

I despair.

Nice idea if only ISIS had a cause other than destruction of Western society.

You have on the simplest solution though. Offer 'ISIS' (whatever it is) a tract of desert in the Middle East to establish their caliphate. Sign it up with international formalities. Encourage others of their radical ilk to go to live there and then 100% destroy the caliphate by miliarty means.

And how did we do it? Total war - nobody talked the Nazis out of their beliefs.

Not that I'm advocating that of course - we've tried bombing these people, and that's probably one of the single biggest causal factors in the rise of fundamentalist Islamist ideologies; every religion has an element of nutjobbery, but very few have the fuel that international policy in the Middle East has provided.

And just for clarity - the decision to raise the threat level to 'critical' is entirely separate from the decision to put the Army on the streets; the latter is nothing to do with JTAC - it's a government decision, and one which conveniently helps to disguise the fact that the police are unable to respond appropriately due to lack of resources - because the Home Secretary (Mrs May) slashed their budgets to ribbons and took 20,000 police officers off the streets.

Good argument, well made.

True enough, but certain clerics facilitate platforms for some of these jihadist speakers.

no chance of this happening police are watching but the terrorists have human rights pity the victims dont

Dialogue with ISIS? And lefties wonder why they're labelled 'loony'.

ISIS don't want dialogue. They want us (the West) dead. All of us. FFS, they want all non-ISIS conforming Muslims dead, so we're not in line for any cosy chats any time soon.

They want to re-establish the Caliphate and spread it across Europe, and eventually the world, under strict Sharia rule. They will kill anyone standing in their way (by a variety of gruesome means, and all on video). They celebrate setting off shrapnel bombs amongst crowds of young girls. Be under no illusion: this is their goal.

Unfortunately the Western liberal mindset is wholly incapable of dealing with this, and of acknowledging the fact our policies of open borders, aggressive political correctness and 'tolerance' are allowing these extremist mindsets to flourish right in our communities, while we're at war with them elsewhere.

I'm a Mancunian. 3 of the victims were local to me. I've felt incredibly sad and heartbroken since the attack - but I'm also angry. And let's be honest, all this 'Love Manchester' stuff is great, but it doesn't actually achieve anything. A vigil, a poem, a few pictures of Muslims smiling with Police officers, people handing out drinks, cafes offering free brews - all very nice and perhaps necessary at this moment, but there's a huge undercurrent of anger being ignored by the press.

Do whatever is necessary. If someone is found to have ISIS training manuals on their PC, lock them up or deport them. If someone is posting pro-ISIS views or flying ISIS flags, the same applies. If the law needs changing, change it. I've said it since 7/7: stop being so nice when so many people want to kill us. Given what we know about Salman Abedi, he should never, ever have been walking the streets of the UK.

And another thing: if I see or hear someone else declaring 'this is nothing to do with Islam', I might huff testily. ISIS follow Wahhabi Sunni Islam, and they are far from alone in this. Everything is carried out in the name of Allah, and there is plenty of support for any attacks on the West. 'This has nothing to do with most Muslims' is more accurate. I don't blame the wider Muslim community, I blame the attackers first and foremost, and I blame us and our politicians for not being willing to take the hard, unpopular decisions at home, while having made some terrible decisions across the Middle East.
