Unless the West treats Islam for what it is, a terrorist organization, there will be no reversal. History has shown repeatedly that when Muslims gain a certain level of political power in a nation, there comes a time when so-called 'moderate Muslims' are dominated and directed by those who apply the Koran as it's written. I.e., the Koran directs its followers to murder, torture and imprison the infidel. Lebanon, Syria, Iraq, Iran, Somalia, Nigeria ... were once nations where Christians could live in relative peace. Islam has made these nations a hell-hole for Christians. Unless/until the West ousts Islam and its followers from its nations, we will have the fate of nations where Christians once lived in relative peace but not anymore. Look at the impact of Islam on France and Britain today.
Centuries ago, Spain got it right. Centuries ago, western Europe got it right. Spain expelled its Muslim population, which was undermining Spain's Christian government and people. The Crusades and past Popes who saw Islam as anti-Christian terrorists got it right! Charles Martel got it right!
Well George Bush (R Kuwait) got it wrong. Iraq was conquered, but no attempt was made to Christianize the population. A lost opportunity.
Has Austria apologized yet for the cruel way they broke the siege of Vienna or pulled down statues of Jan Sobieski?
