The idea is peace through strength. The problem is you have to be sane and so too your adversary. I remember Sting had a song called
Russians.
$1:
We share the same biology
Regardless of ideology
What might save us, me, and you
Is that the Russians love their children too.
The Russians may have been 'godless' (as the propaganda stated at the time) but with religious fanatics with no future anyway like the Wahhabis and Mujahideen who believed that resistance is not futile vs a technological superior enemy one wonders what the future will hold.
