The US was going as far as issuing sanctions waivers to Russia to try and get oil to the market it was so worried about what the war in the middle east would do to prices. All the indications are they're desperate to preserve as much middle eastern oil infrastructure as possible, even to the point where they look like losers vis a vis Iran. No surprise if they aren't inviting tit for tat exchanges on oil infrastructure. And the Russia-Ukraine war had vaguely similar parallels, with Ukraine allowing transit of Russian gas through the country to Europe for ... I want to say at least 12 months. So clearly neither side was so lost in the battle that they thought disrupting the pipelines was a good idea.
That type of targeting discrimination seems to be fairly normal. Armies are only indiscriminate when they think that helps their war aims. Although what exactly the US war aims are in Iran is very much a guess, Trump was struggling to even lie consistently when he was trying to come up with one.
I'm not sure how far the Administration would go but they are very strongly restricted by US Armed forces procedures and just norms.
Show us the difference with Vietnam (and Cambodia).
And the Caribbean.
The notion one would even try to compare 'the Caribbean' - where USN is destroying drug running boats - which is arguably against some maritime laws but is nevertheless exceedingly acute, I think shows how wound up people are in the political context.
There is no relevant kinetic fallout in the Caribbean - it's an Elephant precisely stepping on a single ant.
Capture of Venezuelan Oil ... almost certainly illegal.
But that's a different thing
As for Vietnam - start by laying the context for why the N. Vietnamese imprisoned, tortured, killed 100's of thousands of political dissidents and civilians of all kinds, and continued that horrible repression for decades even to this day as they continue to crack down on mild dissent. The actual facts on both sides are actually ugly, but woefully misrepresented and the same utterly bizarre dual moral lens is applied ... a bit like in the Iranian situation as well.
Implied in the question is the despotism in plain site: why did N. Vietnam invade Cambodia? Against the will of those people? And murder and maraud in that territory?
The difference is between that, as a starting point, and strategic bombing of rural roadways (Ho Chi Min trail) etc., which ironically was in lieu of actually bombing North Vietnam which should have been done right from the onset, would have prevented a war, and saved 1/2 the population from a perennial nightmare and given the citizens some say in their future.
But it's also an example of the extent of the ability of superpowers to project power.
>which is arguably against some maritime laws
You get it completely backwards: the US Navy is "allegedly" destroying drug running boats, and it is completely, totally, "inarguably" against maritime laws - and laws of war (but there is no war, right?) and basic law principles in civilized countries.
>it's an Elephant precisely stepping on a single ant.
It is not a cute animal simile. It is US Navy sailors commiting 200+ summary executions. It is burning alive and drowning. It is widows and orphans.
I mean if we look at all recent wars, Afghanistan, Iraq, Vietnam and now Iran we completely failed in our objectives. We spend billions, kill a lot of people and get a lot of our own people killed and didn't manage to instill democracy anywhere. How is that not losing the wars? It's complete failure to do what we set out to do 3 times now in recent history.
The US generally wins wars, but can fail on occupational and grander objectives, which are different things.
The US 'tied' in Korea, eventually 'won' in Vietnam but then quickly decided to leave - strategic failure), 'won' in Iraq but a grinding occupation left it a strategic quagmire but no total failure.
Middling intervention in Syria was effective in bringing down Assad and now there is a transition to 'something somewhat better'.
There was no fight to even win in Afghanistan as the Talibain was overthrown without direct intervention - the follow up was entirely occupational - and though it was a strategic failure, it wasn't a military defeat. The West just did not want to continue paying the cost of keeping the fighters at bay. That's a 'stupid set of decisions' which is different than 'losing'.
This is all different from Russian failure in Ukraine where it cannot meet it's military objectives.
Iran is shaping up to be a 'military tie' - because US is engaging from afar it' abilities are limited and is taking real losses ... and a pretty big strategic failure, having lost control over the Gulf, no 5th fleet presence in the Gulf, allies attacked, Iran emboldened. Bad.
