I think it's important to stress that the US doesn't rule out a pre-emptive military strike either and the "bush doctrine" (actual name) is the exersize of military might in advance of any real or percieved threat against the united states or its interests.
Of course since we have a pre-emptive strike policy it makes sense that other countries do as well.
You can't look at the russian statement and say "oooh bad, they're evil!" when we've actually implemented the exact same thing while the russians are only talking about it.
If it's a can of worms then by golly it's our can of worms.
I agree totally. This article jumps to some huge conclusions.
Glad someone thinks straight. China and India, I read, also consider such policy, soon Japan and others. US open up new reality so it is normal for all greater power to follow.
