I voted for all of them except:
6d. No Holiday Permits for non-Europeans. (Tourism is Italy's biggest industry)
6e. Cancelation of Diplomatic Relations with non-European Countries (Impractical)
9. In considerable cases, I could imagine granting permanent residences to a limited number of non-Europeans if they are unable to procreate or promise to forego procreation. (They can still damage our countries in a non-biological way)
10. Other (All the above ideas were good enough

)
