[Harry Potter] Did they really need to destroy all the horocruxes first?

It took nearly 14 years for Voldemort to come back the first time. If he died again couldn't they have just destroyed the remaining horocruxes after?

The thing of it is, Voldy's already done all the heavy lifting for coming back with a real body. He's got a field-tested technique and an army that isn't going to scatter to the winds because they know he's coming back. You just kill him without touching the horcruxes, he's back inside of a year. Only get some of the horcruxes and he's back in 2, one to actually revive and another spent fortifying the remaining horcruxes against further assault.

Strategy wise, destroying all horcruxes is the best move. In essence, Dumbledore is taking a page out of Sun Tzu's playbook; Voldemort *thinks* he has a sure-fire exit plan of escape, and will commit himself to any battle, including a doomed one, without realizing his escape route is really a trap. Which is exactly how he meets his end, overcommitting at Hogwarts because he doesn't recognize that the Order of the Phoenix and Dumbledore's Army are running a plan more sophisticated than "stand and die on a matter of principle".
