Thirteen years ago, Muslim true believers flew two aircraft into the World Trade Center towers in New York City, finishing a task they began in 1993 with a truck bomb. Two more planes put a hole in the Pentagon, and in a field in Pennsylvania, killing many more. The last plane missed its' target of either the White House or the Capitol because of the acts of Americans who attempted to retake the plane from the terrorists.
Virtually nothing has been done since to actually face this enemy, although billions have been spent on military operations in Iraq and Afghanistan, and we are probably going to spend billions more in Syria, now. Thousands of Americans have been killed or maimed for little if any suppression of Muslim fanatic terror.
Make no mistake - Islam, as ordained in the Koran, is a deadly threat to all civilization on this planet.
Unless, and until, Muslim leaders publicly deny the Koran as written and evolve to live in peace as the great majority of human religions have over the last millennium, we will always have atrocities such as the beheadings recently broadcast by these Muslim true believers, and more terror such as 9/11. Islam openly promises this to America, and have demonstrated again and again in England, France, and other countries that their only goal is complete subjugation of all who do not bow to Allah.
Islamophobia is a survival mechanism. Learn your mortal enemy, and beware.
And never forget.
