So you're saying that Russia would be a peaceful, friendly nation, except that the military-industrial complex, which is about 5% of the US economy, persuades congress, the State Department and every president (including Obama) to act in ways that force Russia to be militaristic back?
One reason I find this highly improbable is there are lots of powerful political groups that benefit from peace and lower military spending. Are you saying they just stand by and passively let the military-industrial lobby get what it wants? Furthermore, if your conspiracy theory was true, then military spending would be very high, like 10% of gdp like it was during the cold war. Instead it is, as I recall, down around 4%.
The other reason is you seem to be assuming that Putin and Russia are basically peace-loving. That certainly does not fit with Russia's history. I mean, the Russian Empire got to be an empire through a whole lot of military conquest. And Putin was for decades a dedicated communist who believed world peace could come about only through either revolution or conquest. And Russians are highly ethnicist and nationalist, not at all peaceful universalists.
