true, but 1 mile width basically means more empty space, which won't mean much to Gazans. Let Isralies live there, that's another story.
Whaaat?
Much of Gaza is ~4 miles wide (5-6 miles wide in the northernmost part and tapering up to ~7.7 miles in the northern part. 1 mile strip inside the border of Gaza is a ~25% reduction in width.
Let's use a Brooklyn row/train house as an analogy. Many/most of them are 20' (20 feet) wide, and that includes the width of the outer walls, so you end up with ~18' of width. Imagine deducting 4-5' of space, so an 18'x20' livingroom becomes 13'-34'x20', it's quite signficiant. Just visit someone with a 16' wide Brooklyn row house and you'll notice a signficant reduction in space.
In any case, there were many thousands of strucures leveled in this buffer zone over the past year.
