Last week, Iran claimed it was banning "companies in which the Zionists have any shares."
So I humbly suggest to my Israeli readers to buy exactly one share of companies that Iran heavily depends on, and publicize that fact.
Some examples include Linde, BASF, Lurgi, Krupp, Siemens, ZF Friedrichshafen, Mercedes, Volkswagen and MAN.
If the world isn't taking the sanctions against Iran seriously, maybe Iran can be forced to do it itself!
