Islam first took Jersualem, Antioch, and Alexandria. The Islamic conquest meant the majority of the Christian population at the time fell to Islam.
Then they took Constantinople, and shattered the Orthodox states.
Rome means that Western civilization has collapsed, and Islamization of the West will prevail.
Muslims may be crazy, but they actually know history and the value of symbolism.
The Nazis were crazy too but they did an awful lot of damage before they were done.
