Obama was referring to the attack on 9/11/2001, not bengazi
Obama's address was mourning the loss of four Americans who were killed the day before in an act of terror.
I can cite the address - all you do is lie about it:
No acts of terror will ever shake the resolve of this great nation, alter that character, or eclipse the light of the values that we stand for. Today we mourn four more Americans who represent the very best of the United States of America. We will not waver in our commitment to see that justice is done for this terrible act. And make no mistake, justice will be done.
Remarks by the President on the Deaths of U.S. Embassy Staff in Libya The White House
"No
acts of terror will ever shake the resolve of this great nation, ... We will not waver in our commitment to see that justice is done for
this terrible act. And make no mistake, justice will be done."
In the same paragraph Obama refers directly to "this terrible act". He is not referring to ten years earlier. You can quit your lie anytime.
