Reporter in a speech that offered no new tactical ideas to combat islamic terrorism, donald trump said the battle can not be won until the enemy that is radical islamic terrorism is named. We have a president that doesnt want to say the words. Anyone who cannot name our enemy is not fit to lead our country. Ep repeated this false claim. I was a an opponent of the iraq war from the beginning, a major difference between me and my opponent. Reporter trump did not publicly express sceptsd similar about the u. S.

If my son were still i and i said all those who are there, the threat to their life has gone up a couple clicks, gone up a couple clicks. Reporter biden went so far as to say that if his son had been deployed by a president trump, he would have thrown himself at his sons feet to prevent him from going.
