Muslims believe that the Mahdi will come as the deliverer in the last days.
Islamic Mahdi or Messiah
Mahdī, (Arabic: "guided one") in Islamic eschatology, a messianic deliverer who will fill earth with justice and equity, restore true religion, and usher in a short golden age lasting seven, eight, or nine years before the end of the world. The belief in the end-time Mahdi is almost universally accepted across all Sunni and Shi'a Muslim denominations.
Appearance of Mahdi
Before his reappearance (Arabic: ظهور, romanized: ṭuhūr), the world will plunge into chaos, where immorality and ignorance will be commonplace, the Qur'an will be forgotten, and religion will be abandoned. There will be plagues, earthquakes, floods, wars and death.
So as soon as the powerful West (so-called godly Christian nations) led by US legalized homosexuality and same sex marriage and uses the UN Human Rights to force the whole world to accept these detestable abominations that the Muslims believe that the world has plunged into chaos and their Mahdi will appear soon.
So Muslims are bolder and are fearless in fighting for justice with the extremists preparing the arrival of their Mahdi. Their war cry is 'Allahu Akbar' or 'Allah is great'
The Iranians (esp. the Twelver Shia) believe that the Mahdi is living in their midst and he will appear to deliver Iran when Iran is about to be destroyed by its enemies. Then he will lead Iran to conquer the whole world for Islam.
That is why the Iranian leadership has been provoking Israel and its powerful allies of US and the West to attack and defeat Iran to hasten the appearing of their Mahdi.
Iran Supreme Leader
The present king of the North is the 84 year old Supreme Leader Ayatollah Ali Khamenei. He is Iran's spiritual leader and highest authority - he has the final say over all government matters in the country.
Ayatollah Ali is constantly warning the US that if they or Israel attacks any of its nuclear site, he will send his full arsenal to wipe out Israel and all US military bases in the Middle East.
With his strong faith that the Mahdi will appear soon, I believe Ayatollah Ali will send his limited, outdated and inferior arsenal of weaponry to attack the invincible US fleets knowing very well that it will be suicidal, for he was hoping to witness the Mahdi's appearance and his amazing power in annihilating the invincible US forces.
