Many believe the battle for the northern city is going to be long and bloody and it isn't clear when the ground forces will actually enter the city.
There are many civilians trapped inside Mosul and their fates are tenuous as ISIS may use them as bullet-stoppers and basic human shields like Hamas does with Palestinian children.
Early Monday morning, convoys of U.S., Iraqi and Kurdish troops moved east of Mosul along the front line as U.S.-led airstrikes bombed the crap out of the jihadists.
The sky was filled with plumes of smoke, sending Leonardo DiCaprio flying back to his therapist's couch. (He burns a lot of jet fuel going around the world in his private jet, complaining of those who burn a lot of jet fuel flying commercial.)
The military move came soon after Iraqi Prime Minister Haider al-Abadi announced the start of the operations on state TV.
"These forces that are liberating you today, they have one goal in Mosul which is to get rid of Daesh and to secure your dignity," al Abadi said, as he addressed the city's residents. "God will [aka "Inshallah"] we shall win."
And then everyone screamed "Allahu Akbar! Allahu Akbar! Allahu Akbar!"
This operation to retake Mosul will be the largest operation in Iraq since our troops left in 2011. If successful, it will deal the biggest blow to the Islamic State since they learned that Israel invented Intel, SMS and lots of things they use.
