When Mohammed was kicked out of Mecca for being too violent, the Jews in Yathrib invited him to live there.  The first thing Mohammed did was build a mosque.  Over the next years he convinced the Jews to let more Muslims move into town.  When enough Muslims were living there, they killed all the Jews.  Thus was born the Muslim Doctrine Of Immigration, the Hijra (hish'ruh).

Barack Obama was America's murderous Mohammed.  He installed Muslim Brotherhood (MB) operatives into federal offices of power.  Egypt, Saudi Arabia, UAE have banned MB as a terrorist organization.  So did Ghadaffi and Saddam Hussein while they lived.  Obama's MB operatives scrubbed FBI, DHS, ICE, CBE and all other federal anti-terrorist training materials of the words jihad, islamist, terrorist, caliphate, etc.

Muslim Brotherhood is a terrorist organization:
