Show me a country that doesn’t bother other countries — ever — and I’ll show you a country that doesn’t have any cards to play. Except for maybe isolated island nations who lack the ability to threaten anyone, all nations come into conflict with others and the only ones that “don’t [initiate aggression with] others” are the ones who lack the ability or who have done the calculation that they’d be severely slapped back if they tried, so they wisely don’t poke the bear(s).
Well said. No organism willingly commits perceived suicide unless it's a viable strategy for its continued existence. The reason a thing exists, is because it hasn't tempted its potential predator.
