It is question number 70, not 70%.

Below copied from page 25 of the document you linked:

Q70) Concerning armed attacks against Israeli civilians inside Israel, I.... Total West Bank Gaza Strip 1) Strongly support 23% 16% 34% 2) support 34% 32% 36% 3) oppose 27% 34% 17% 4) Strongly oppose 11% 10% 12% 5) DK/NA 11% 10% 12%

It is notable that "Strongly support" is twice as high in the Gaza Strip, where the Israeli military has built a wall around it and has maintained an indefinite ongoing land, sea, and air blockade on since 2007.
