Just like we entered Karabakh, just like we entered Libya, we might do similar to them.
Türkiye didn’t “enter” into either of those countries with its own troops. Rather they used Syrian mercs, and provided technical support, including “selling” their drones.
I don’t think what he means is sending in troops in this situation as well. Türkiye (or rather, maybe, Erdoğan’s ruling party) has existing strong ties with both Hamas and Hezbollah.
So my assumption on how this translates would be arms shipments to Lebanon. I don’t think they can get anything in to Gaza. And I don’t think either Lebanon or Palestine would welcome Syrian mercenaries.
