Other countries probably focus quite a bit more on the defense aspect. How many times has the US military countered a hostile attacking force? Instead, I can think of significantly more instances where the US was instigating the situation.
That may be partly true, but in recent times, most western countries participated in wars like Afganistan and Iraq, and provided logistical or other support during the current Iran war.
US military power does most of its heavy lifting without throwing bombs. We're seeing the end of Pax Americana and it isn't pretty.
You dont really understand globalism and pax americana do you?
But specifically yes america has been directly attacked 20 times in the last 40 some odd years... so averaging once every other year.
The US stopped countless wars from starting in the first place due to deterrence. Look at Ukraine to see what happens to a country that isn't part of an alliance like NATO.
