So far, they are not funded to do this for that long. They have floated a $200B bill to congress, which made national news coverage. It would start a huge, prolonged fight over the war and actually force them to ask permission from congress to fight it (barring totally disregarding the constitution which is still a possibility).

Unfortunately I can very well imagine several more months and years of this. We are still fighting a forever war that started in 2001. This is all a generation of Americans will know, and that is sad.
