Re "U.S. set to act alone on Syria" (Page A1, Aug. 30): The United States is either a member of the United Nations or it is not. If it is, it cannot choose independently to interfere with another nation because it has been offended by what that nation has done within its borders.
The British Parliament decided that Britain was a member of the United Nations when it refused to allow its prime minister to act independently to intervene in Syria because of that government's use of chemical weapons within its borders. It is assumed that the United Nations will not use aggression against Syria because Russia and China will veto that action. Russia and China have that authority because when the United Nations was formed, the United States and other superpowers insisted that the other superpowers have such authority.
President Barack Obama had no authority to draw a red line that Syria could not cross.
