Will the Kurds be used by America to launch a war on Iran?

Supporting non-state actors is always a very dangerous game. Many such groups have purely bad intentions; seeking to creating discord, instability and war. Even with the best of intentions, it is dangerous to support inherently unstable non-state actors in geo-political conflicts.
A recent example was the US use of the terrorist group and non-state organisation KLA (Kosovo Liberation Army) to destroy what remained of Yugoslavia in 1999.

BREAKING: Turkish and Kurdish forces fighting in northern Syria

According to al-Masdar, Kurdish YPG forces are currently engaged in combat with Turkish forces in Afrin. The northern Syrian region has been under the control of Kurdish led SDF forces since 2012.
This masks yet another escalation of Turkey’s ‘Euphrates Shield’ operation which has seen Turkish armed forces with their allied jihadist group FSA occupying Syrian land.
