There is an interesting thread on the Russian aggression in Georgia on Austin Bay's blog.
Mr. Bay addresses some possible options available in the current situation, as well as some options that clearly aren't.
FWIW, I've never been a fan of "Peace Keeper" Units. You train soldiers to soldier, and if you end up using them for something else, you task it as an additional duty.
Soldiers exist to execute national policy by direct violence. Anything else is just a euphemism. Folks would be much better served if they kept that reality up front.
And you can hit any recent thread over at Belmont Club for more excellent blogging on the subject.
I have a few comments scattered through those discussions, but I'm too depressed to try to put together anything for here.
It's like watching reruns, it is.
The real question is which U.S. political party will be the first to formally surrender Georgia? It looks like President Bush is attempting to insert U.S. (and EU or NATO) forces under the aegis of "relief" as a mechanism to stop the Russian aggression, but the Russians are simply making noises about truces and cease fires as they prepare to consolidate their hold on Georgia permanently.
Aside from candidate posturing, there has been zero press on congressional or senate resistance to the Russian aggression that I have heard about.
I bet that President Bush NEVER thought it would be that lonely at the top.
