1) you implied that the US is perpetually at war and Iran is not, my argument was that it's literally the exact opposite. In fact, let me point out, it's even worse than that. Of the 2 or 3 superpowers that exist, the US is by far the most peaceful one, in fact it's the only one that ISN'T perpetually at war.For the last 10 years, Russia has been at war with Ukraine, and China has been at war, meaning regular kinetic exchanges with ... everyone really. Especially Taiwan, but also Korea, the Philippines, Japan, Vietnam, and, perhaps surprisingly, Russia. In the last 10 years the US has not had any war, and I'm betting everyone kind of understands that compared to Russia's war, the US war with Iran is not even at the level Russia would call a "war". Not even remotely close. If exchanging missiles and long-range drones to and from ships counts, Russia has been at war with the northern and southeastern countries of the EU for pretty much a decade (meaning both the East Sea with Finland/Denmark/Poland/Sweden... and Turkey + Mediterranean countries on the other side)
And yet, somehow people seem to be convinced of almost the exact opposite of the facts.
Oh and the propaganda both the extreme right and the extreme left in the EU, as well as state media in Russia, are spreading is that the EU is attacking Russia (not the US, that is not a typo, that the EU is attacking Russia), even separately from the Ukraine war. That is the main factor why EU countries are so convinced Russia is close to a large scale attack on the EU. And it also of course means that at least Russia does not care in the slightest who is a threat to them and who isn't. They only care who they perceive as weak. Frankly, the same goes for Iran. Iran is not remotely threatened by the UAE, Saudi Arabia, Yemen, Kuwait or Qatar, and yet they're attacking all of them (they're even attacking Saudi Arabia with land forces by the way)
2) As to your second point, Iran was constantly attacking oil facilities pretty much their entire existence, if you include tankers, for at least 40 years, it was just constant. It was "normal", and barely reported. When it comes to land-based infrastructure attacked things heated up and cooled down, but never cooled down fully.
The US defended everyone, and the tankers, and by defended I mean we blew the hell out of Iranians, usually sinking boats, occasionally going after fixed installations. I don't think you're going to find many US Navy sailors surprised at what's happened.
Outside of that here is a list of attacks on gulf state energy infrastructure, just the last 6 years. You may notice that either by the location or the associations (e.g. Houthi attacks) it's always been Iran doing the attacks since Saddam Hussein left, with the occasional shot in the other direction. I couldn't find a good recent example, but actually it's not just Israel shooting and fighting back, but also Syria, Saudi Arabia, and Iraq. Iran isn't even at peace with the Taliban.
