1. I would abolish all armed forces and create only one highly-technological army. 
2. There will be only one global tax for the upkeep of the army; otherwise, it would be a free global economy.  
3. I would put transnational corporations under strict regulation and take all banks under governmental control.
4. I would replace the ruling class in each country with my representatives who would be chosen not by the popular vote but on the meritocratic basis. 
5. I would keep the national (cultural, linguistic) diversity and even encourage it.
