I believe we will have to learn to fight differently, again.
It was pounded in over and over and over -in DoD & Civvie k-12 schooling- that the only reason we defeated the British in the 1770s is that we broke the European rules & fought like the Indians did. Brits adapted soon enough, its become the standard we still use today, but they didn't adapt in time. Seems like (for those of us in the states) we don't learn from our own history.
Our ROE don't work. That simple. From Vietnam onward for the US, not sure about other nations but I know there have been heaps of conflicts other have been engaged in we haven't even touched... Each and every single time we face this kind of fighting, things go badly. Conventional warfare cannot meet it.
Superior numbers is not an asset. Superior weapons are not an asset. At least, not the way that either is used. Concentrated forces just provide a target, not strength. Like the columns of old.
I don't have a solution. I'm not that clever.
Certain ideas, though, I'm sure occur to most of us. And the public would hate it. Seems like as long as you don't know who you're killing, it's fine. Unless they're photogenic. But just going off of how we crucify people working off good intel, much less bad... I don't know. Like I said. Not that clever.
