At some point it boils down to one of two options: (1) pushing for a bill with a firm withdrawal date and hoping that continuing to hold votes on a bill will somehow garner a veto-proof majority in the Senate wherein 17 Republicans cross over; or (2) passing no legislation whatsoever and thereby cutting off all funding for the wars in Afghanistan and Iraq.
Opting to do neither seems perfectly reasonable because (1) isn't happening and (2) is reckless.
