Wars lasting as long as they do doesn't have anything to do with the calibers used by the military.
and everything to do with politics and poorly defined enemies
Although the first Gulf war...how long did that last? 6 months?

The SAS is unhappy it seems with their 5.56 Nato rifles and are lusting after FN SCARs in 7.62 Nato. I see both sides of the discussion, I like my .45 acp handguns for home defense but like the .223/5.56 for my rifles. Of course the SAS and other soldiers are probably shooting at longer ranges than I am. What say you?
Id say .300 blackout would be a good compromise for them. I dont think it would be to difficult to convert their existing rifles to that cartridge would it?
The argument over 5.56/7.62x51 is debated constantly in many forms. But there is no denying that (all things being equal) a heavier projectile is going to be less effected by the elements than a smaller, less stable round. That's why the 338lap and 50bmg are designated long range rounds. They simply kill better at range.
The issue is stopping power in an engagement, not lethality.
The 556 is great for suppressive fire. It's great for wounding. But it's not great for killing.
I find that hard to believe unless the laws of physics changed. A slower moving projectile of the same approximate weight has more energy?
The reason they're interested in 7.62x51 rifles is because in Afghanistan these days many fights start at 400+ meters and never get much closer than that. Unlike Vietnam, the bad guys in this one learned early on that attempts to grab ISAF forces by the belt buckle in a firefight is a losing proposition. Since we're incredible restrictive over there with supporting air and artillery, small units are having to fight it out with what they have organic to themselves (I think almost every bad guy killed in the province I was in on my last trip was killed with a .50 cal or either an M240 or the MG3s the Italians used, for instance).
