As an EU member Italy is obligated to follow the laws of the EU.
Breaking those laws means facing an EU court and whatever punishments dished out to individuals and the country for breaching those laws, even sanctions.
The EU is the biggest threat to Europe. Not Russia, not China.
Countries are being forced to total islamisation by the EU. Don't comply? They get less money and have to pay huge fines.
Basically a fascist system.
