Avid,
Your comment displays your young age, lack of experience, and/or your lack of knowledge regarding our history and responsibilities in the world. Do we have problems here at home, absolutely, but this country is without doubt the greatest place to live in the world. I don't see immigrants dying trying to cross the borders of any other land but this one.
I know as a part of my profession extreme Muslims are a threat to our way of life and the west in general. Our enemies have learned that they cannot meet our military head to head on defined battle lines. Instead, they use guerilla type tactics hiding any country that will permit, utilizing schools, hospitals, and churches as safe havens. Also, remember it is not out of the realm of possibility for long time adversaries like China or Russia to employ these radical thinkers to do their dirty work.
For 8 eight years we watched, beginning in 1993 with the first World Trade Center bombing, as terrorists attacked us at home and our interests abroad with virtually no response. Well, in 2001 we fought back and kill extremist terrorists everyday, diminishing the next attack here that may take the life of one of your loved ones. Just as the video stated, "freedom isn't free", every so often we ask our fellow countrymen to preserve it. God Bless them all and God Bless the USA.
