This is a curious decision.

Military experts wonder how effective the pursuit will be, given that the EU wants to avoid civilian casualties under all circumstances. Political experts wonder how chasing pirates ties in to the overall political strategy and if even there is one. These doubts explain why the mission has not been met with overwhelming enthusiasm. Spain, Ireland and especially Germany had serious reservations.

German lawmakers will need to approve the extension of Atalanta when Chancellor Angela Merkel presents it to the Bundestag, or German parliament next month. (The German cabinet meets on April 18 to discuss it). Lawmakers are already asking many questions.

How deep into the shore will the helicopters go in pursuit of pirates?

“We can’t tell you the exact details but it will not be too far inland,” a spokesperson for NAVFOR Atalanta replied.

EU diplomats say the distance will be about two kilometers, ”That’s very far in,” one European Parliament lawmaker commented.

And how will the EU be able to distinguish between boats and equipment belonging to the pirates as opposed to those belonging to local fishermen?

“We have information about the pirates’ camps. We will be targeting logistic dumps close to the shoreline. That includes boats, fuel and ladders that are close to the shoreline,” NAVFOR added.

But what happens if the pirates use civilians as human shields against the EU helicopters?

“We are aiming specifically at the logistics of the pirates,” NAVFOR continued.

 The EU will put no troops on the ground. It will drop no bombs or rockets. But it will use machine guns.

Germany’s opposition parties are not impressed with such details. The Social Democrats and Greens are expected to vote against the new mandate, as will the Left Party. It is even hard to see Mrs. Merkel’s center-right coalition agreeing unanimously. The defense ministry has some reservations.

Gernot Erler, the Social Democrats’ leading foreign policy expert and deputy parliamentary leader says the operation could turn into a Mission Creep.

Reinhard Bütikofer, the leader of the German Greens in the European Parliament, is more critical. “Attacking pirates' infrastructure on land, including from helicopters, doesn't make a lot of sense militarily once pirates start using human shields or moving further inland,” he told Carnegie Europe.

Mr Bütikofer was concerned too that the mission could lead to a high intensity conflict between EU forces and armed groups that have nothing to do with piracy.

As an alternative to the new EU missions, he proposes strengthening the legal dimension of counter-piracy actions by bringing pirates before strong and competent courts and doing away with the current catch-and-release practice.

At best, however, this would be a short term measure. Somalia is a failed state plagued with famine, instability, a weak government and powerless institutions. It is also a haven for Al Qaeda supporters.

The country needs a long-term policy to bring stability and jobs and end sectarianism. Catching pirates is not enough. Europe needs to do some hard thinking about its strategy towards the Horn of Africa.
