It is in this vital national security interest of the United States to prevent and deter the spread and use of deadly chemical weapons.
There can be no dispute that Syria used banned chemical weapons, violated its obligations under the chemical weapons convention and ignored the urging of the UN Security Council.
Years of previous attempts at changing Assad's behaviour have all failed and failed very dramatically.
As a result, the refugee crisis continues to deepen and the region continues to destabilise, threatening the United States and its allies.
Tonight, I call on all civilised nations to join us in seeking to end the slaughter and bloodshed in Syria.
Also, to end terrorism of all kinds and all types.
We ask for God's wisdom as we face the challenge of our very troubled world.
We pray for the lives of the wounded and for the souls of those who have passed.
We hope that as long as America stands for justice, then peace and harmony will, in the end, prevail.
Good night and God bless America and the entire world.
Thank you.
