I said it earlier, Turkey who has nutured these terrorists scums, and who still surprisgly has as objective/aim(as stated by Erdogan recently) of toppling Assad, and leaving a power vacuum to be filled by these islamists beheaders(just look at lybia today, saddled with militias and no central government.
) will come back to hunt turkey just like Pakistan who did the same with the mujahideen/taliban in Afghanistan. You cant expect to support/finance/provide sanctuary and ammunitions to rag tag islamists fighters/militias/rebels/jihadists and expect they wont cause instability in your neighbourhood and eventually turn against you when your interests don't match anymore.
Moreover the more this conflict goes, the more arms the gulf states/west/saudi arabia etc will keep pouring weapons in the region to the 'Moderate syrian rebels'
the more arms the Kurds and other islamists militants will have, and the more instability/risk Turkey will face. The PKK will also benefit from this conflict no matter the outcome. Turkey is the only country who will come out at loss from this. It was indeed a big mistake to support the rebels in the first place. Turkey should have remained neutral and distance itself from this a la Jordan. Taking sides(the wrong one for that matter) was a huge mistake Erdogan made, whats even shocking is that he hasn't learned from his mistakes at all, he keeps going the same direction
Our governments can still afford to play this game of supporting these extremists and 'moderates' for geo-political reasons/interests since we are far away from the region and we have no border at all with these troubled region called the middle east. But Turkey's case/situation is different since it has a large border with both Syria and Iraq. so its decisions/views should be different.
I expect things to get alot worse for Turkey before they get any better in the coming moths/years.This is just the beginning.
Will be interesting to see what happens this coming days/months.
