From Assad's brutal violence to hold on to power by any means necessary.
Putin's Russia and Iran propping up Assad.
Maliki's sectarian corruption.
Baghdadi's apocalyptic cult ISIS.
Erdogan's grab for more power and abuse against Kurds.
The House of Saud and Saudi clerics bankrolling Wahhabi Salafi propaganda.
Iran's support of Hezbollah in Syria and Shiite militias in Iraq.
Israel's abuse of power against a stateless people.
Bush's short sighted invasion of Iraq.
Obama's failed red line in Syria and seeming indifference.
American foreign policy rocks between the aggressive and the passive always reacting to the last failed policy. The doctrine of doing stupid shit to not doing shit. Bill Clinton failed to help Rwanda during its genocide because of what happened in Somalia when Bush 41 went in. President Obama failed to help Syria because of the previous Iraq invasion by Bush 43.
The United Nations uses highfalutin idealistic language but lacks the collective will to back it up. The system protects the interests of the strong and lets the weak fall into oblivion.
All of these leaders from East to West are either incompetent, indifferent, corrupt or purveyors of brutal violence on the citizens of their countries. These leaders will either not use their power to protect the vulnerable or when they do use power it is to kill and crush dissent. They are either too aggressive or too passive and the price is the blood and death of the Syrian people.
