Ramadi is mostly Sunni Muslim

When the Secretary of Defense says something like: "The Iraqis don't want to fight", it really doesn't tell the whole story there.

First of all, Ramadi is Sunni Muslim but most of the fighters in Baghdad who would be fighting for Ramadi are NOT Sunni they are Shiite Muslims like Iran.

Second, they don't want to wind up on youtube having their heads, hands, legs or manliness cut off while screaming either as they die. Because this is a part of the REAL war there too which is completely psychological.

So, when the Secretary of Defense says, "The Iraqis don't want to fight" this isn't the whole story. The war is suicide bombers with trucks filled with explosives (ten or more of them) with explosions bigger than the one in Oklahoma when hundreds died in the 1990s in the government building there.

ISIS has always been and likely will always be (as long as it exists) Asymetrical Warfare or unexpected or terrorist or Guerrilla warfare. In other words what they do usually cannot be predicted by anyone. When they come into a new territory or when they leave a territory is always equally unexpected.

I'm sure armies and military men around the world will study ISIS tactics for hundreds or thousands of years because it is both so effective and terrorizing on the local opposing armies and populations.

Another factor most Americans don't know is that Sunni Tribesmen in Ramadi were not given weapons by the Iraqi government so hundreds of them died trying to defend their families with basically nothing.

This is the other relatively unspoken problem also in Iraq that the U.S. Congress is trying to address directly now too.
