The Washington Post is lying here

"The exchange of fire took place in a contested area known as Shebaa Farms. Hezbollah says the area belongs to Lebanon, and the United Nations defines the area as part of Syria. The Israelis claim it is theirs." The Post changed the language and it claimed that Syria claims it was Syrian which is a lie as the Syrian government said more than once that it is Lebanese. The notion that the UN defines the area as "part of Syria" is, in international legal language, bullshit. The UN does NOT define which borders are between countries: this is an ignorant belief common among March 14 politicians in Lebanon and the Post correspondent in Beirut reproduced the propaganda talking point of March 14 without realizing that it is not true.  Countries demarcate borders among them and they simply deposit the agreement with the UN. The UN has no role whatsoever in demarcations.
