According to many human rights experts, Israeli actions over the last few decades constitute a genocide upon the Palestinian people. The US honors international laws, and passed the War Crimes Act of 1996 to further emphasize our commitment to stand against, rather than support war crimes.
If Israel insists on taking up arms against the Palestinian people; let it be a brightly colored arsenal of fun for the whole family. And unlike conventional weapons, use of Super Soakers on children is actually encouraged. Which should allow the IDF to get some aggression out of their systems without angering those pesky human rights groups.
