I don't think anything that has been done has actually added any significant safety.
How about ending our presence in Iraq? Do you think that has anything to do with your safety? It does. Allow me to explain.
Check out this wiki page. Give it a good once-over, then let's talk about the contents.
You'll find that a good base number for civilian deaths in Iraq is a little over 100,000. That seems to be the average agreed upon number. We'll go with the AP number, 110,600 deaths. AP is reliable, and it's a decent average for the most conservative estimates for loss of life. Now note the time period. "March 2003 to April 2009." That's 6 years and one month. Are you with me so far?
On 9/11, the terrorist attacks accounted for the loss of 2,977 lives. Now let's look at those numbers and see what they mean.
110600 / 2977 is 37.15. So what that means is that we have killed 37 times more civilians than the 9/11 attackers did. The 9/11 victims and the civilians in Iraq are alike - all innocent people that did not deserve to die.
March 2003 to April 2009 is a period spanning 6 years and 1 month. That's 73 months. And 73 / 37.15 is 1.96. That's almost exactly two months. That means that what we've done to Iraq is like a 9/11 style attack every two months for over six years. Remember how pissed off we were after 9/11? Imagine that every two months for six years running.
110,000 families missing a loved one. A child they raised, a mother they loved, a father that will never come home. 110,000 families that have a good solid reason to absolutely poisonously passionately hate our guts.
Still feel safe? It took only 19 guys to carry out the 9/11 attacks.
My point is that it absolutely matters who is President. Decisions will be made that will affect your safety directly. You need someone at the helm that makes good decisions.
It matters. A lot.
