Now, there are multiple actors fighting ISIS.

we have the Syrian Government, Russia, china and Iran on one side.

We have the Free Syrian Army, Saudi, libya and the west (us, uk, france).

How does everything come together? Well sweden is considered the untemperamental humanitarian party, and also a part of the UN security counsil. However, sweden is not part of NATO. This will close sweden closer to NATO, which automatically forces Finland to join in. How?

There will probably be a call in the UN to take forces on the ground, and NATO will take the task. Swedens role in this, is to remove the possibility to veto it in the UN which russia will try to do. "The use of the veto must be limited – especially in cases of mass atrocities such as in Syria" http://www.government.se/opinion-pieces/2017/01/sweden-takes-its-seat-on-the-un-security-council/

Turkey has interests, israel has interests, saudi has interests, so with nato there, the powerbalance will switch. When syria falls, everyone wants their piece of the cake.

I'm just shitting words here, but heres at least one conspiracy. Feel free to discuss the flaws.
