Pro to the question "Is a Two-State Solution (Israel and Palestine) an Acceptable Solution to the Israeli-Palestinian Conflict?"
"Israelis do not trust the Palestinian Authority (PA) to fulfill its security obligations and halt terrorist attacks, while Palestinians remain convinced that Israel will never voluntarily cede the West Bank and Gaza... A properly designed West Bank security fence could help dissipate the mistrust and violence while facilitating a two-state solution."
