If the Islamic Republic regime changes, what happens and why are leftists, Islamists, and some neighboring countries so against it?
1) Hezbollah, Hamas, and the resistance forces will be completely wiped out.
2) Instead of Iran’s money going into the pockets of Arabs and resistance groups and being spent on building nukes and fueling chaos and war it’ll be invested in rebuilding and advancing Iran.
3) Iran will regain its millennia old prestige, and love for Iran and patriotism will replace Islam-centric loyalty.
4) Thanks to its massive potential, Iran will with domestic and foreign investment and a tourism boom overtake neighboring and Arab countries again, just like before!
