There are several flawed arguments in this piece. It is an oversimplification to say that Israel returning to 1967 borders will not affect Taliban etc, but it would greatly affect the politics in those countries mentioned, and the effectiveness in their eliminating extremists. While those extremist groups may have sought widespread, Israel's actions would surely have provided them with that support. Another flawed argument is that one needs to look at these extremist groups for adverse affects of Israel's push for greater Israel. On the contrary, the justifiable political opposition to Israel due to this and many other Israeli actions, in middle east and beyond, including large percentages of their populations, is both more threatening for Israel, and more reason for Israel changing its policies, and returning to the 1967 borders.
