Easy solution!
Have Israel purchase these, or better yet, LOAN them on a "lend-lease" type plan...
Have the Phalanx systems overlapping the areas that the Hamas-holes launch from, with a mobile fire control system. If need be, they can be mounted on mobile platforms.
Once launch is detected, the Phalanx opens up on the missiles, blowing them up so the drop on the PaleSimian side of the border, so THEY take the casualties!
Let the UN scream, let the Islamazis cry foul...who F'n cares. As long as they never leave PaleSimian territory, Israel would be safer!
Phalanx, huh? Pretty cool machines, kind of like R2D2 with an attitude. I never actually saw one of those until I'd been out of the Navy for a decade, but they were always on my advancement exams.
