Let's stop pretending that the terror perpetrated by Islam is in retaliation for the war in Iraq and Afghanistan. There was no war in those countries when Muslim men rammed planes into the World Trade Center and the Pentagon killing almost 3,000 people of many nationalities and faiths.
The terror in Europe by Islam has only one purpose that is the total domination of Europe by an Islamic Caliphate. This invasion is not the first attempt by Islam to take over Europe. They have tried many times in the past. This time they can not come with sabers, as they would be defeated immediately.
They now have a ten step plan to domination. Their ten steps to domination begin with infiltration, demands for special treatment, threats and coercion, and finally physical action to take over.
