This, oddly enough, has been a recurring daydream of mine. An Orion drops out of subspace and proceeds to blow the top off of a couple of mountains as a means to provide defeat to the enemy and victory for whoever deployed the Orion.
I fully expect to be silenced by deletion or at least heavily edited since my speech isn't free because it is in opposition to the opinion of the ones with the power.
The problem with asymmetric warfare is that it's usually not asymmetric enough. In order to have victory in a conflict, you either have to have a set of well defined rules that are universally agreed upon and enforceable on all parties or the enemy, whether it's true or not, has to believe that you will do whatever it takes to gain victory. You can't fight a war against an enemy that won't fight you himself but instead manipulates others(usually the ones that will suffer if they win) to fight for him and have a hope of victory.
The problem with "The War" is that the people running it on both sides don't want victory, they want political capital they can use to gain power. This is worsened by the fact that we, by and large, don't live in a society that understands the concept of victory or individual exceptionalism. We live in a society that seems to think that everyone can "win". This flies in the face of the reality that for any party to gain victory that has to be someone on the other side who doesn't.
This is true in every facet of life including work, play and relationships. If you get a raise at work, let's say it's mandatory in your union contract, then someone somewhere is a little closer to losing they're job. If you are having a go at some footie or chess or whatever, when the game is over someone will have lost. When and if you get married or what have you, you and your spouse can be said to have gained victory in your relationship, however, someone else, possibly close to either or both of you who was secretly carrying a torch for you or your spouse can be considered to have lost.
I'm babbling a little bit I know, but conflict MUST end in victory for one side or the other, otherwise there's no point to it.
