"U.S. abuses and provocations, (Iran?)," - this is a two sided coin.
Tangibly, sure, but not really. Iran followed the nuclear agreement, the U.S. violated it and has been openly escalating ever since. This does not mean Iran is an angel, but it does mean the U.S. is the aggressor here.
As an European, China, Iran etc. do not hold the moral high ground in world affairs in my opinion, but that's kind of expected, few think they do. What seems to be the case is that somehow the U.S. thinks it still holds that ground, where I find it not to be true not only internationally, but increasingly domestically too.
And because U.S. citizens have the most power over their own government, I think holding it to account should be of the highest priority when voting.
