Sadly, Mosul is now a pile of rubble.
“drove” them. Why not shoot them? No need to herd them up again next week.
“they drove Islamic State militants from some of their last strongholds in Mosul”
“some”?
This was the biggest battle of the last decade, and the biggest urban battle since Stalingrad.
ISIS lost its biggest jewel, but its losses have been mounting on several fronts - recruiting has virtually ended, revenues are drying up, headcount is dropping by around a hundred per day, and key leaders are being lost at a significant pace. Not widely reported is that the remaining ISIS elements in BenGhazi Libya were just routed about a week ago as well.
Everyone now expects them lose, which is helpful. If they could not hold Mosul, how could they hold smaller things? After Raqqa in Syria falls (a tenth the size of Mosul), the remaining ISIS strongholds get smaller - Tal Afar and Hawija in Iraq, Deir ez Zour and Mayadin in Syria. the last stand will likely be in the Euphrates River Valley in Syria, or at the Iraqi/Syrian Border at al Qaim/AbuKamal.
There will probably be continued significant military operations the rest of this year (likely longer) to clear those areas and turn control over to non-ISIS groups. as long as ISIS controls any land, they can still technically (under sharia) claim a caliphate.
