I seems imminent that Obama is going to get us involved in Syria. Despite all the warnings from Russia, China and Iran.
Is it your assertion that we should decide foreign policy and a course of action based on "warnings" from Russia, China, and Iran? That is absurd.
It seems to be obvious that Syria is using chemical weapons against it's own people. This is a tragedy but, these weapons do not pose a clear and present danger to the US.
This is a gross violation of pretty much any international norm you can think of. It is a tragedy. We have to do something, especially after we declare that their use is unacceptable and a "red line". We lose all credibility with everyone if we do nothing. Iran won't think twice about running to finish a nuclear weapon, it will destroy our credibility in the ME with those friendly governments who we share/get vital intelligence from.
The downsides to any action are of course massive, which is why we are faced with bad decisions all around -- the worst of which being the establishment of a "red line" to begin with. A few days of bombing will accomplish nothing.
Why in the world would we intervene in Syria?
Because Obama went off teleprompter and established a red line. And credibility is that important.
