You win wars by not only destroying your opponents war machine but also its will to fight. That will to fight is just not in its armies but also it population that backs that machine. Too bad we don’t have any leaders that are willing to take that will from our current enemies but wants to take that will from their own people.
I love what Gen. Patton said, you don’t win wars by dying for your country, you win wars by making the other SOB die for his country.
