Nothing is sure.
But with the word "surely" involved, the answer has to be no. Without that word, it's a lot harder to answer.
After the Soviets withdrew, Najibullah's regime held out longer than anybody expected, and the civil war that erupted afterward was also worse than anyone had feared. Some of the factors that contributed to that, and to the subsequent rise of the Taliban, would not be repeated if the international troops were to leave today. But there are a whole host of new and different factors that would affect the outcome, some for the better and others for the worse.
In short, I have absolutely no idea.
"over some of the country" = they already have.
"over more of the country than they already have" = probably yes, though it's not clear how much more.
Lots of factors to consider, but I think there are areas of the country where they'd run into serious resistance.
I need to log off now.
