Imagine thinking selling oil has anything to do with army or self production of weapons. Just look at russia man, you can't have a more proper example than this.
Russia creates own weapons, own missiles even, submarines etc..., has shittons of oil and look at them xD their economy is still garbage. Just like Turkey's economy will be garbage if you think erdogan can do anything towards USA. Honestly, i don't like USA but turkey has no foot to step on towards USA's economy. Only way to do it is a huge economical crisis that will ruin the USA.
Edit: Oh besides, Erdogan kept bringing up that treaty, but you know very well it's just another lie to win over votes and people; he's been doing this for a long time. Imagine believing a narrative that they suddenly can drill oil in cyprus fields, EU/US will sanction turkey and then to who would they even sell oil? lol to vietnam? gratz they barely will make you strong... Nobody will buy your parts of weaponry either wtf. You are living in a lie mate, use your common sense and don't rehearse what that propaganda merchant erdogan is saying.
