President Obama should think 25000 times before he gets involved with the Syrian situation via the outside Syrian opposition.
Relying on those will be similar and just as treacherous as when the US relied on reassurances from the Iraqi secular outside opposition who assured Bush at the time that the US should help the Iraqi people and get in, and American troops will be welcomed with rice and flowers.
Yeah well, we saw what happened next!
Arab "Secular" opposition groups are all double-faced when it comes to their relationship with the US, and those working from outside their countries have Zero credibility among the local population.
The US in the MENA region is blamed for every ailment these people suffer from, whether we get involved or not, it doesn't make a difference.
