Your list of countries has a glaring omission.

Let´s see what I can come up with in under a minute, mmm, seize properties and money from any business hiring illegal immigrants and use that money to pay for deportation flights, place sanctions, carrot and stick, on any country bordering the EU that allows illegal immigrants to sneak in., seize any money illegals make in the future and use it to deport them, cancel bank accounts for illegals, mine the border with Turkey, constitution amendment guaranteeing that an illegal will never get a passport in his life.
