Baghdad is under water as failure to repair infrastructure gives birth to high risk of disease, crushed small economies, and chaotic disruption. The yearly budget spent runs between US$600-700 BILLION dollars.
Some are getting quite rich as the people continue to suffer. Corruption runs deep, and cash flows to cronies who are accumulating the vote-getting power of the purse. Abadi's words are strong, but he faces an entrenched base who are loath to see a successful cleanup.
Maliki, who built much of the network of cash flow to friends and political allies, retains power in the Dawa party and is capable of neutralizing Abadi's best efforts.
So, the people will continue to suffer until they gain control, and that ain't gonna be easy.
