>Why is this relevant on HN?

Aside from this being politically and potentially ethnically/religiously divisive...it is historical. You have Turkey invading Syria to use force against a militia funded/armed/trained by the US. In response the US President took to Twitter to essentially say go in and kill everyone, we have no interest...meanwhile another politician from the same party took to Twitter to tell Turkey not to go into Syria, because, well the US Congress hasn't authorize them to.

Its ridiculous and important, but goes to show while people are dying in armed conflict, for which we are in some ways responsible, our highest political leaders are taking to Twitter.
