"Turkey has presented a detailed plan to oust Islamic State from its Raqqa urban stronghold in northeastern Syria and strategy discussions with the Trump administration are under way, according to Erdogan’s spokesman, Ibrahim Kalin."

That plan should be easy, 
Step 1. Stop buying ISIS oil, laundering their money, selling them weapons and providing military intelligence.
Step 2. Convince the Saudis and Qatar to do the same.
Step 3. Tell the US not to "accidentally" bomb Syrian forces and "accidentally" drop pallets of weapons near known ISIS locations.

War over in less than a month.
