what right does israel have for this level of killing?

where does israel get this kind of killing power? From the USA. Reports of american attacks usually say 'an F-15 dropped such and such bombs' but when foreign armies are using US war machines, they seem to leave that part out. Id like the beirutreports to say 'israeli-owned F-15s bombed beirut today'.

i suggest lebanon give back the two IDF soldiers.
