Erdogan has been seething over our support for the Kurdish groups for years, in fact he was asked not to interfere in Syria when he wasn't included in the coalition to start with, and he ignored that....add in Washington’s refusal to extradite his Fethullah Gulen, that he blames for Turkey’s 2016 coup attempt, then the issue over the the S-400 no-sale.....not to mention his support for Isis......sooo He's not exactly a favorable participant in US diplomacy....he's backed himself into a corner.

I am not saying he is a good actor but generally there is no problem with Saudis aiding ISIS and they are brutal to opposition too. Such US allies as Greece and South Korea has a 50/50 mix of US and Russian military equipment in their inventory and East European NATO allies actually has more Russian than Western stuff.
