Rwanda was a population-level event, so it was lots of little groups everywhere, who aren't wearing uniforms and aren't abiding by the Geneva conventions or anything else really organized. Armies don't deal very effectively with that kind of thing. Police forces are generally a lot better at that kind of thing, but in Rwanda police were part of the problem. I don't think an army could have done anything effective there.
On-topic, I think that most of the current conservative political platform is pretty sound, and exactly what we need after 6 decades of big government. Unfortunately, politicians tend to ignore platforms after they get elected.
The latest crop of Republicans being actual conservatives was a nice surprise. We could do with more of that, I think. They at least got Congress moving, and put the fiscal discussions back on some kind of a fact-based ground. Just a start, but better than Obama-the-Ostrich.
Some of the conservative platform is bull, but so is a bunch of the liberal platform. I think the big-government-healthcare-for-all has definitely been proved to be unsustainable in the long-run, though. Britain and Europe can't even keep it up, and they've got high US healthcare prices and US tax breaks subsidizing quite a lot of medical research. Also, medical tourism for basic healthcare happens in Europe from what I hear, as opposed to the medical tourism for plastic surgery that's popular in America. That says a lot about how cost-effective and convenient medical care is in Europe to me, if people have to travel to get basic dentistry, etc. Same thing with Canadians - they'll freely admit to coming to the US for specialist procedures, etc, that are available here but can't be gotten or can't be gotten without a lot of agonizing expense and waiting in Canada.
If the US switches to a more price-controlled model, I think a lot of medical care will simply become unavailable even for those who can afford it. That's already happening to a great extent with Medicare, Medicaid, etc. A lot of doctors simply won't take anyone on those plans anymore because they don't pay enough and the paperwork is so frustrating, even if the person can afford the premiums and co-pays. Supplemental private insurance plans are a big business for people on government plans.
