So if we violate them what the Brussels dictatorship will do?
For starters, Italy won't violate them. For the same reason even Britain didn't violate them and instead went through the very long, tedious and expensive procedure of article 50.
If the EU had no "power" over its members as you like to claim, do you think for a second that Britain would have gone through all that trouble?
Why didn't they just say "screw you, we are gone and we do as we like"? Isn't that what you would be expect them to do if it is indeed true that the EU has no power over its members (and in the brexit case, it even concerned a LEAVING member!!!).
Having said that, Italy depends on the EU for a WHOLE BUNCH of things. Free travel, free trade, commissions of all kinds of things, money, etc.
The EU doesn't need to send tanks. It can simply start shutting down services one by one in proportion to the gravity of Italy breaking EU law.
For example: cut them off the free market. The result of which would be a whole bunch of empty shelves and even power outages.
You are a typical person who has NO IDEA how much a full member country like Italy actually depends on the EU for all kinds of things.
And it's in Italy's best interest btw... this dependence is not like Italy being a "slave" of the EU.
It's more like "strong together and weak alone".
You might want to read up how your comfortable luxurous life in Italy is made possible in large part as a direct result of EU membership.
Will they drive their tanks across the Alps to exterminate us?
Come on...
No need to.
Germany openly violates them, and nobody says anything.
How so?
