Never said it whom?
And the "massive barrage" of rockets isn't hitting anything.
Thanks to US tech.
At the very least you could return a little on that investment.
1. rockets killed and injured dozens of Israelis over the year, suppressing the south of Israel-ONLY THE ROCKETS.
2.Israel never said operation Protective Edge will be a "surgical strike" as you said, Israel did say they will strike Hamas VERY HARD if they won't stop the violence, later on the tunnel system discovered and forced the IDF in this situation, it was well known tunnels cannot be destroyed by air force only and luckily it didn't explode in our face with the massive terror attack Hamas planned.
3.US Funding, Israeli tech, development, testing - that's the difference.
4.The very least Israel returning in that little investment is the fact Israelis are ******* meat machine in the middle east, the only true ally US can depend on, and this is the smallest investment so far if you really want to know.
