Just because people on the internet did not understand that doesn't mean the parties involved did not know that.
Every single diplomat knows it, which is why diplomacy is about horse trading. Parties want to "sort of" maintain the status quo, even if it means giving up some of what is "rightfully their" by the agreement.
You expect the whole world to be familiar with the intricacies of the US Government. I assume that you have taken the same interest in familiarizing yourself with the technicalities of the Serbian government agreeing to international treaties.
What you now is the same as everyone else what’s being sold in the media (even social media). There are lots of hacks like Thomas Friedman being given lots of page space in papers such as NYT to even spread propaganda for powerful interests. In aggregation these hacks represents alignments of powers which even a president cannot surmount in the long term. Obama of course understood this but didn’t give up on what he thought was right, and now Trump does not care about was is right instead he simply surf the waves of narratives spewed by the conservative/alt-right to both winning the presidency and keeping his hold on power and enrich himself in the process, while he claims he’s being backstabbed by the deep state. But it’s clear his bet on the wrong horse is becoming a hazard as more Republicans in Senate are realizing this and changing course to avoid the risk of complete collapse of their party and American morals.
I guess another Vietnam has to happen so that the American people will again learn the real news, but given the assymetry in military power and outsourcing of it to allies like SA I’m not sure if they will learn this time.
The staggering amount of these untruthful statements I read on a daily basis here and elsewhere on the internet is extremely disconcerting and increasing at an alarming rate. Please do not try to criticize Trump unless you are able to do so effectively. Posts like yours only make Trump's deceit and dishonesty harder to challenge, by damaging the credibility of anti-Trump individuals. Worse yet, they do nothing to further the cause of promoting positive change. Because if you want to do good, you do have to get things right.

Pulling out of a loophole in a treaty is something any country can do. Why is US especial in this?

Worse, instead of owning to this change of mind, the rationale of technicality is used in order to justify pulling out. This is done in bad faith.
> The nice thing about the American system is that while treaties are difficult to pass, they are more or less permanent.
You say this now. This experience shows that, once you want to pull out, you will find a nice loophole to pull out. That is the "more or less" part.
And there is another aspect: once excuses for pulling out have run out, we know that the US will simply break, whenever and for whatever reason it wants, existing, ratified, seal-proof treaties.
The US is simply untrustworthy. And sneaky.
