That's why Vietnam, Iraq and Afghanistan were a cakewalk - regular people with guns can't possibly resist predator drones and the like.

What you are actually missing is that guns are part of (some American's) tribal culture. The move to ban guns is mainly, at this point in time, a front in the culture wars. (Historically it was also about disarming blacks in order to empower terrorists.) There are many cultural artifacts and other enjoyable practices which kill people; Britain's drinking culture, gay sex (http://www.cdc.gov/hiv/basics/statistics.html), etc.

Gun control is mainly about attacking one of the cherished cultural values of our tribal enemies, in much the same way that Bush-era "faith based $X" or opposing various gay things is.
