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.
