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.
Even if the EU countries would agree, this does not seem realistic to me, when considering countries like Switzerland. They are located in the middle of the EU and the popular right wing people’s party of Switzerland is supposed to have ties to Russia. Borders to neighbouring countries have several points that are hardly controlled, especially to France.

This is whataboutism. This thread here talks about Russia. If you want to talk about Israel, it may be a good idea to open another thread.
