Survival instinct is lined with fear. Fear for losing life causes attachment and aversion, craving and hatred, friends and foes, etc., thus creating all the problems in the world, wars, warming, wipeout of species, etc.
Wars and warring machines are therefore from fear, cowardice and weakness, not security, bravery and strength. Fearless ones live without wars and weapons.
Fear comes from small self (bubble), not from limitless life (ocean). Global truth and global ethic come from transcending small selves (individual, social, nantional, religious, political, economical, cultural).
Stopping fear and delusion can be done by stopping karma (action and action result, habit), sitting calm and clear, eventually reaching unconditioned peace (nirvana) and unsurpassed awakening (bodhi).
