There is nothing you or I can do about dead soldiers. Or the scores dead from 911.
It is asinine to blame ONE PERSON, i.e., the president. Most decisions of such magnitude are made by collective minds.
I respect the office of the presidency. Whoever holds it gets my respect. If you live in the US, he is your president, as well.
I practice self responsibility, not that you don't. I am a product of my actions or inactions, so the finger of blame always points back to me.
Thus, I do vote. But, I never get sore at the polititions. They do not even know I exist.
