I'm all for letting the rest of the world sort out its problems while we focus on our own. We just have to stick our fingers into every loving pie we see don't we?
its less sticking fingers in every loving pie and putting in some sort of effort to prevent other countries doing stupid stuff that leads into larger worldwide problems
for example, the world wars started with individual countries and the alliances that ended up in things loving up. we can't just ignore the rest of the world, cause other countries like the UK may have vested interest in Turkey not becoming a fascist country, and we can't just ignore our alliance with the big countries without severely undermining our status in the world or potentially screwing up our trade relations >> diminished economy.
