I think the only reason that the actions by Israel in Gaza haven't been branded as "terrorist" is simply because of the Israeli-US relationship, without the condemnation from US, which usually follows acts of atrocity when they do not benefit them, there would be considerably more coverage of the matter, and Israelis would be branded for what they are - essentially the real terrorists of the Middle East. The rocket statistic may be bullshit, but Israel does have the advanced technology, courtesy of US, to prevent such missiles from hitting targets, hence why the death toll was something ludicrous 200:1 before the ground forces moved in.
The death toll in Palestine also consists of incredibly high percentage of civillians, showing their lack of regard and bullshit of the "We're only targeting Hamas" mindset, which is really hard to believe when so many innocents are killed when they've only been given minutes warning to scramble the fuck out of the house.
Israel is getting its hands dirty and abusing the technological advantage that they have to essentially destablize the Middle East and justify the killings.
I do remember reading somewhere that ISIS has claimed responsibility for the murder of the 3 teenagers, and Hamas has continiously denied it, whereas the Palestinian teenager that got burned alive was killed, by admittance by the Jews residing in Israel. Kind of shows the contrast of the situation.
