The globe might feel stable while sitting inside the US and reading domestic media sources, but it sure hasn’t been easy for the dozens of countries we’ve been invading/occupying for the past decades.
If we're making sweeping generalizations, then countries with stable benevolent governments who don't threaten their neighbors / the US and fund terrorism don't get invaded or occupied either. To be clear, I'm not saying every foreign policy action the US has undertaken in the last few decades has been superb.
If we're making sweeping generalizations, then countries that don't project military power to prop up dodgy regimes and enforce their currency on major commodities don't get targetted by terrorist action. To be clear, I'm not saying every action that resistance organisations and foreign governments have taken in the last few decades has been superb.
Of course this is all a challenging exercise (which is my only real point) since we don’t have counterfactuals for any of these scenarios.
