^Possibly, but Picard was afraid Starfleet would collapse in 6 months or so. If the Klingons were only going to last 7 months themselves, they'd still win. But then what have they won? A hundred or more ruined worlds? A populace continuously straining to overthrow them? An empire so large that they couldn't hope to hold it without being contaminated by the cultures and ideals within it? Or would the Klingons consider it a good game, pat themselves on the back for being the victors, write some operas about the better battles, and leave the UFP to pick up the pieces of itself, with perhaps some tribute being sent to Kronos on a regular schedule?
They never said how the Klingons were doing in the war.
