In 2009, 150.000 irregular migrants were intercepted in Greece, which amounts for 75% of all interceptions in the EU. Even though in 2010, this number is likely to drop again, it is clear that the closure of other routes to Europe (West Africa to Spain, Libya to Italy/Malta) has made Greece the presently last remaining gateway to the EU, turning it into a embattled ground where the EU is intervening decisively.
There are three tested responses to irregular migration, and the operations of Frontex in Greece and the Aegean have elements of all of them. The first would be to integrate Turkey into the border regime (similar to the case of Libya). On an institutional level, Frontex is trying to connect with the Turkish coast guard and to involve them in joint maneuvers and also seeks a working agreement with the Turkish border authority. But also Greece and the EU are trying to improve their cooperation with Turkey on migration matters: While Greece and Turkey have a readmission agreement (which Greece would like to extend, since practically, its functioning is questionable), the EU has been negotiating such an agreement for many years with Turkey, albeit without success so far. Functional readmission agreements would force Turkey to readmit not only nationals, but all irregular migrants who can be proved to have entered Greece and the EU via Turkey. This would shift the responsibility for securing borders and inhibiting the movements of migration to Turkey.
