Heck, you are right about Schengen, but I am not sure about the requirement of a popular vote in this case. In article 17 about the agreement between the EU and Switzerland it is written that Switzerland can terminate the agreement. There is nothing mentioned about the referendum. Digging deeper in Swiss laws, the Federal Office clearly states an “optional” referendum, NOT a mandatory one.
I hope you can well imagine how Le Pen, Trump and Putin are opening champagne bottles about these riots. These rioters couldn’t shoot better in their own knees and causing a critical situation for the entire EU and for themselves - it increases economical instability, because potential investors will step back, rendering any solution more difficult, and it increases the chance that Le Pen will win the next election - a loss for Ukraine, a loss of freedom, an increase of imbalance and instability for the entire EU.
Sorry, but everybody supporting these riots - protests are something different - is IMHO an enemy of the EU, a supporter of the three above mentioned people and their agenda.
