All of these countries are either failed democracies or dictatorships. Not sure where you are from, but it’s in my interest that democracy remains strong. If that means sanctioning non-democratic countries when they want to undermine democracies, then so be it.
Not sure why you are bringing up all the wars the US has been involved with or what US’s foreign policy is. I’m not from the US and never said I agreed with their behaviour. I do, however, agree with protecting democracy through economic or military means.
