Not 'murican, but will give my five cents.
Middle East is a very complex geographical location, that can be by far stable. With Israel, Syria, Iran, Gulf countries and now-liberated (!) countries with people in power, who are Islamic extremists (like Muslim Brotherhood) - it creates a bad, bad mixture.
Turkey is pro-Morsi and against the coup d'etat, while it also is anti-Israel. Morsi was anti-Israel and was okay with Syria, not Iran. Iran is pro-Syria and against Israel, but against Morsi, as he was, from their point of view, put there by western imperialists. Plus, they are not with Turkey. Gulf Countries are with Turkey and United States, but also are against Morsi.
Simply put, Middle East is way too complex, militarized and unstable. People are allies and enemies with both their allies and enemies.
Furthermore, Russian Foreign Minister stated why the heck would Syrian Government use chemical weapons while the UN Investigators were there. Understanding the Free Syrian Army, is actually not Syrian nor free, and their members are Turkish, Chechen, Arab, Afghan, Kurd, Iraqi and African, rather then Syrian.
Assad is not innocent. But the western governments needs to understand something, after Iraq and Afghanistan. Those regions NEED dictators. Before the "liberation" of Iraq from Saddam Hussein, there was NOT A SINGLE bombings. Now, everyday, at least once, dozens of people die from the blast, many more severely injured. Afghanistan had a very, very oppressing regime indeed, however now, with terrorist attacks, bombings and gun fires at every single part of their region, it is much much more destabilized. Libya, "liberated" by French, perhaps also had an oppressing regime; however with the worlds perfect social care and welfare system. Now it is also destabilized with much much worse condition. And Egypt? Hah. Yeh.
Sure, keep liberating nations after nations. Though remember. It is not because of the sanctity of preserving and protecting human life. It is just for economical gains, while thousands die in conflicts.
