Power move on the Israeli foreign minister’s part, I have to admit.
Assuming those who leaked it remain unpunished, they just made it harder for anyone to hold secret meetings with Israel. This is actually quite bad for them in the medium term.
Even if that was their aim, it would be an incredibly short-sighted move. Most countries benefit from the ability to conduct diplomacy in private; this goes doubly for MENA nations, and triply for Israel in the context of its relations with these nations (many of which -
formally - do not maintain relations with Israel at all).
Israel has always had more important goals than giving Libyan politicians a bad day, and (unfortunately) there are "cheaper" ways to do that than compromising their integrity like this.
