The people of Iran also want regime change. If it could be achieved by economic strategy that would be excellent.
The globalists, like those behind the Atlantic Council, want constant tensions in the ME. Their end game is a devastating nuclear war between "Zion" and "Islam" to achieve global population reduction and to bring "order out of chaos". President Trump is a threat to the globalist schemes and plans and so all malign actors are ramping up their rhetoric and attacks against POTUS and USA. If they want to assign blame for current tensions they need to look in the mirror.
