All candidates "commit a series of boners". In one of the GOP debates, Trump was asked about the TPP and he went on a long rant about China. China isn't part of TPP. At the "commander in chief" forum, Clinton said "we will not put ground troops in Iraq and Syria" - we already have troops in Iraq and Syria. HRC also said "we're going to put a lot of coal miners out of business".
Regarding Aleppo, nobody outside of Syria would know what/where Aleppo is without the destabilizing hyper-interventionist policies of Bush, Clinton, et al.
Regarding the "admired foreign leader", most of 'em are crooks, tyrants, socialists and/or warmongers. Not much for a Libertarian to admire there, eh?
