Iran's proxy militias have caused the decline of Christians in many regions by adopting ‘forced immigration’. In Lebanon Hezbollah targets missionaries, impedes conversions, imposes strict dress codes and alcohol bans, and limits mixed sexes in public, in what have been dubbed ‘mini-Tehrans.’ A sizeable amount of land owned by Christians has been taken over by Hezbollah through eviction. In Iraq, initially employed to resist American forces, the Shiite Mahdi Army has changed the demography, Making Baghdad 'Christian-free' was high on its agenda when they morphed into IS. Iran had influence in Syria through the Assad family (Alawite Sunni). After the uprising Iran restructured the Syrian Army and created several militias within the Shia Liberation Army. It saved the Assad regime, killing 600,000 people, displacing 6.5 million internally, and forcing 6.6 million to flee Syria. In Yemen the Houthis have invested considerable effort into ending the Christian presence in the territories under their control.
