As Israel and Hamas have resumed negotiations in recent days over a deal to free Gilad Shalit, the lobby against a deal has enjoyed unprecedented exposure.
Hamas is demanding that in return for Mr Shalit, an Israeli soldier abducted in 2006, Israel frees 1,000 Palestinian prisoners, including some who have launched attacks on civilians.
Mossad chief Meir Dagan and Shin Bet director Yuval Diskin are known to have deep reservations about the proposed exchange, including fears that freed prisoners will perpetrate more attacks and that Hamas will capture further soldiers. Yet grassroots efforts to publicise arguments against a deal have had very limited success - until now.
A satirical animation, which mocks the immensely popular campaign for a prisoner exchange, has received almost 160,000 viewings on YouTube since it was posted earlier this month.
