“The call to form a national emergency government is a coup against the constitution and the political process,”
He is a correct. They have a Constitution that was written under the critical eye of the US and UN. What is done should be under the provisions of their Constitution.
However, under the power of the administration he has wreaked havoc by reducing the effectiveness of the military, purging Sunni generals, firing Sunni bureaucrats, etc.
This part can be turned around, but it is probably too late.
Even if it were a good idea, I don’t think this is the time to do it. Overlooked is the fact that the big Shiite leader in Baghdad has called not only for Shiites but for Sunnis and Kurds to fight against ISIL. Also, ISIL was perfectly happy to kill Sunnis in the (Sunni) area that they swept into first. There probably is a fair amount of unity among people opposed to ISIL.
This fight is only marginally connected to the conflicts between the Sunnis and the Shiites. It’s really an attack upon the very concept of a secular civil government.
I bet the “coalition” that Kerry wants, in all of his naivete (or ill-will) would actually be something where ISIL, which is an international terrorist group and not even Iraqi, would have a dominant voice. In other words, hand over Iraq to AQ while chirping about a “unified government.”
