Are we going to let them win?

"Did Syria and Iran win in their indirect war on Iraq?
This question has been occupying my thoughts in the last few days and to reach an answer, we should first know the goals of the US in the region and whether these goals have been failed or they're merely witnessing slow progress?
And are we going to see some determination on reaching these goals or are we going to see strategic changes from offense to defense in the plans?"
