You can't get closer to the heart of national sovereignty than national security and intelligence services.
There is a series of sectors which could be severely disrupted by terrorist attacks, particularly if they were to happen in several member states simultaneously.
There have been hundreds of European arrest warrants issued. Extradition used to take up to a year now that is down to two months.
The European Borders Agency in Warsaw has been created to help border forces in Europe cooperate more.
Terrorists have failed in what is arguably al Qaida's most important objective - to trigger revolutions.
Terrorists always have the advantage of surprise.
Our strategy should be to strengthen the hand of moderate Muslims.
Muslim organisations tend to have a low level of organisation. The communities in Europe are quite diverse.
Look at Iraq look at Afghanistan, where at great personal physical risk people have gone to the polls and have rejected the appeal from Bin Laden and his allies to stay at home.
It's important that we work very closely with moderate Muslim forces locally, nationally and internationally.
Indiscriminate attacks on civilians ought, under all circumstances, to be illegal in war as in peacetime.
In intelligence work, there are limits to the amount of information one can share. Confidentiality is essential.
If you exchange information internationally, you must strengthen data protection. Those are two sides of the same coin.
If you combat an international phenomenon, it is indispensable to share information internationally.
I remain optimistic. What we've seen in Europe and the rest of the world is that freedom has a much stronger attraction than radical fundamentalism.
We're still stymied by the old stand-off between those who wish to fight terrorism and resistance fighters.
We still lack a global definition of terrorism.
We remain vulnerable. There is no such thing as 100 percent security against terrorism.
We have 13 global conventions on aspects of terrorism. Unfortunately, so far only one-third of the world's countries have ratified all 12.
We are familiar with terrorism. But indiscriminate, cross-border, religiously motivated terrorism is new.
There are no automatic links between poverty and terrorism. Among millions of poor people in the world, only a few turn to terrorism.
The central role in the fight against terrorism is with national authorities.
Europe has a long and tragic history of mostly domestic terrorism.
We have adopted a programme of legislation to combat terrorist financing and make it more difficult for terrorists to travel across borders.
The idea is to have global standards. There is so much travel that if you just had a regional standard, it would probably ultimately have to be changed.
