The EU needs to act on Libya. If it doesn't, the consequences for Europe – in terms of migration, energy revenues and support for terrorism – could be disasterous. Here are eight concrete steps that European leaders should consider taking.

Tunisians see Europe as complicit with the old regime of President Ben Ali, and were disappointed by the slow reaction of European leaders to their revolution. But they are willing to forgive, if their neighbours to the north makes amends by offering prompt and generous help as they rebuild their country.

Tunisia's democrats have made an amazing start, after launching the wave of popular uprisings that are continuing to rock the Arab world. But they worry that the world will forget them as they embark upon the massive project of rebuilding a new Tunisia.

Libya is in chaos, and Colonel Gaddafi seems determined to hang on to power at any expense. But he has already lost control of large swathes of the country, the security forces and bureaucracy, and it is not premature to start planning for a post-Gaddafi Libya.

If there ever was a need and an opportunity for Europe to show its muscles, Colonel Gaddafi is providing one. The test is a different one for the EU after the turmoil in Tunisia, Egypt and beyond, but European leaders can no longer look the other way.
