Minuteman follows the bouncing red ball: "The buck stops everywhere."
So that "red line" wasn't drawn by Obama but by Congress and the world and maybe George Bush. Funny thing, though, is that the White House Press Secretary didn't quite convey their complicity:
We go on to reaffirm that the President has set a clear red line as it relates to the United States that the use of chemical weapons or the transfer of chemical weapons to terrorist groups is a red line that is not acceptable to us, nor should it be to the international community. It's precisely because we take this red line so seriously that we believe there is an obligation to fully investigate any and all evidence of chemical weapons use within Syria.Emphasis added for credit and/or blame. In fact, this statement clearly does not include the international community but - hey - now it does. Because the time has come to seek an accomplice.
