And how does ISIS have enough people to hold these towns? Was there no sign of possible Iraqi Army collapse before this? Were they Sunnis or Shiites? Are the Shiites just incapable of performing as an Army?
If being in the army means nothing more than a good paycheck then you will not stand and fight.
Just because you've paid people to put on a uniform, doesn't make them an army.
If they aren't willing to fight, they are not an army. The ISIS men are willing to fight, the Iraqi army is not. We will see if the Iraqi Shiites and Kurds can put together a real army before being overrun.
“Are the Shiites just incapable of performing as an Army?”
I think they’re mostly just unwilling to die defending Sunnis from other Sunnis. War will start in earnest when they reach Shia territory.
I don't believe that it does. It certainly does have enough people to destabilize the sitting government, though, putting Iraq up for grabs at the hands of a number of parties who have been just waiting for the opportunity. If Iran isn't already actively involved it soon will be.
