Sure Turkey won't keep quiet if Israel invades Lebanon Erdogan will keep huffing and puffing the way he does now and continues to make empty threats and speeches and empty speeches never hurt anybody. There is no way Turkey will go to war with Israel over Lebanon. Erdogan is there to encourage Lebanon to become an Iranian satellite state as Iran & Syria are 2 of his best friends these days. When he goes home he can feel safe in the knowledge that Israeli jets will continue to make overflights and if Hizbollah provoke a war then Israel will not be worrying about the threats this little man makes and it will defend itself.
